I'm a creationist fundie first off, and I was wondering how one could be an evolutionists.
Hello, creationist fundie, nice to meet you.
The reason someone would accept evolution is pretty straightforward: It's because neo-Darwinian evolution is the most widely accepted explanation for how the diversity of life came into existence. If one wanted to change the mainstream science, the most direct way to do that would be to study the topic and write papers proposing a scientifically reasonable alternative; request that the papers be peer-reviewed and published in a mainstream scientific journal; and then hope that your work would be persuasive enough to change the prevailing understanding of biology. It's a tall order, sure, but it's the way that scientific inquiry generally proceeds these days, and it's been very useful at developing a body of knowledge that has resulted in the technology you enjoy today, such as that computer that you are typing on.
I could go into many topics, however I feel the need to just touch up on a few, being the geologic strata, the fossils, and anything else pertaining to that.
Firstly, the geologic strata are completely vague and arbitrary, the transition imperceptibly. A scientist cannot just go out and dig to a certain depth and know right then which stata it was. As said, they cannot even tale when they've transitioned into another strata until they run into fossils (will cover later) or conduct 'radiometric dating'. Also within this vague and arbitrary strata, it is extremely variable and the stratas are only accepted when they coincide with the presumed fossil age; which the fossils are dated by the rocks and the rocks are dated by the fossils for some nice circular reasoning. So, say, if the scientist 'knows' the age of the strata and finds a fossil within that very arbitrary and undistinguished strata, then the fossil is the same age, while if the fossils are presumed to be a certain age and they find one in another strata then they date the strata accordingly along side the fossils. What is this? If a fossil is in the wrong spot, then they attribute that fact not to the flaw of evolution, however something cataclysmic, that no one knows what, moved it there. I thought science was supposed to be based off evidence and fact, not wishful thinking that some great event might have caused something to happen.
Jeff Dee has already pointed out to you an invaluable resource in the Talk Origins Archive. However, I would like to draw your special attention to a subsection of that site known as the Index to Creationist Claims.
If you do a word search on that page for "strata" you will find numerous articles, including one which directly addresses your question. There is a brief response on this page. There is also a longer explanation of the science of dating fossils, on this page.
If you read these articles, what you discover is that there are actually a variety of separate methods for dating a fossil, all of which tend to produce similar answers, and therefore are used to independently verify the age of a fossil. The geologic eras were thus determined after various dating techniques were already common, and after observing that similar fossils tend to fall in similar orders within layers of rock. The reason it's now additionally possible to date fossils by the layer in which they appear, is because the strata have been so well established by other dating methods.
How come there are so many fossils? They would not formed over natural causes because in order for an animal to become fossilized, it must occur very rapid and a quick death. Surely not ALL of these fossils died like that. If they did, why doesn't that happen anymore? We do not have anything close to that happening today.
Of course not all dead organisms form fossils. Only a very small fraction of the animals that ever lived are fossilized. Multi-cellular life spans over a period of about 3-3.5 billion years, and as you rightly pointed out, the vast majority of those organisms do not leave fossils.
So what caused it? Well the Flood did of course!
Unfortunately for your hypothesis, the idea that there was a worldwide flood is not taken even a little bit seriously in mainstream science. There are a multitude of problems with the flood idea, which you can brush up on here.
In particular, I think my favorite example of such problems is the fact that other cultures, such as Egypt and Sumeria, had thriving cultures which lasted right through the supposed dates of the flood. For example, the Egyptians were building pyramids both before and immediately after the supposed flood dates. That would be a neat trick -- I wonder if the new Pharaohs were Noah's grandchildren? And how many of their cousins were enslaved to do the work?
Here's some quick little proofs for it (I could go into many biblical accounts, however I know that you atheists folk aren't to keen to accepting it):
1. World-wide distribution of flood distributions
2. Origin of civilization near Ararat-Babylon region in post-flood time.
3. Convergence of population growth statistics on date of flood
4. Dating of oldest living things at post-flood time
5. Worldwide occurrence of water-laid sediments and sedimentary rocks
6. Recent uplift of major mountain ranges
7. Marine fossils on crests of mountains
8. Evidence of former worldwide warm climate
9. Necessity of catastrophic burial and rapid lithification of fossil deposits
10. Recent origin of many datable geological processes
11. Worldwide distribution of all types of fossils
12. Uniform physical appearance of rocks from different "ages"
13. Frequent mixing of fossils from different "ages"
14. Near-random deposition of formational sequences
15. Equivalence of total organic material in present world and fossil world.
16. Wide distribution of recent volcanic rocks
17. Evidence of recent water bodies in present desert areas
18. Worldwide occurrence of raised shore lines and river terraces
19. Evidence of recent drastic rise in sea level
20. Universal occurrence of rivers in valleys too large for the present stream
21. Sudden extinction of dinosaurs and other prehistoric animals
22. Rapid onset of glacial period
23. Existence of polystrate fossils.
24. Preservation of tracks and other ephemeral markings throughout the geologic column
25. Worldwide occurrence of sedimentary fossil "graveyards" in rocks of all "ages"
26. Absence of any physical evidence of chronological boundary between rocks of successive "ages"
27. Occurrence of all rock types (shale, limestone, granite, etc.) in all "ages"
28. Parallel of supposed evolutionary sequence through different "ages" with modern ecological zonation in the one present age
29. Lack of correlation of most radiometric "ages" with assumed paleontological "ages"
30. Absence of meteorites in geologic column
31. Absence of hail imprints in geologic column, despite abundance of fossil ripple-marks and raindrop imprints
32. Evidence of man's existence during earliest of geologic "ages" (e.g., human footprints in Cambrian, Carboniferous, and Cretaceous formations)
It looks to me like you're just grabbing long lists of items that you found on web sites, but can't be bothered to back them up with any detail. Hence, I can't be bothered to respond to each one individually. If you would care to read more of the Index to Creationist Claims, you will find a lot of responses to these canards there. If you would like to pick out one or two of your bullet points that you find particularly persuasive, then I would be happy to discuss them in detail after you expand on them.
Finally, what about the dinosaur drawings in places like Arizona and Rhodesia and many others? In those times, they didn't have a concept of a dinosaur, they supposedly didn't know anything about those. So, how did they know what they looked like? Some are phenomenal at their accuracy.
Thanks for reading and I look forward to hearing back from you. Thanks:
Whether they're phenomenal or not is a matter of opinion, I suppose -- I'm not all that impressed myself. Short answer: people imagine all kinds of cool monsters. Longer answer: here and here.
