The whole theory of (macro)evolution is based around an (extremely) old earth. 4.5 billion years. There is no proof of an earth that old.
Right now someone's probably about to get started on carbon dating and other so called "accurate" forms of testing how old a sample is to prove me wrong. Don't bother. With a little research (try researching the other side of the argument for once) you'll find that it's inaccurate. Long story short, samples that we know for a fact are twenty years old come up as being two-hundred thousand or whatever the case.
As far as fossils go it's even worse. They date layers of earth by what kind of fossils are found there, and they date the fossils by what kind of layer it's in. It's circular reasoning.
Next, we have the moon. The moon is 238,855 miles away. You may or may not know that the moon is moving away from the earth at a rate of 1.5 inches a year. That would mean when life first came into existence, the moon was about 132,321 miles away. (238,855 minus 1.5 times 4.5bil divided by 12 divided by 5280) Needless to say, with the moon that close life would have had a hard time getting started.
Those are just a few things that come to mind that might interest somebody to research.
That being said, what's the point of debating? Every topic around here is the exact same. Does anyone ever change their beliefs because of what some kid on Blockland Forums told them? I certainly hope that isn't the case. Most evolutionists and Christians (on these forums in particular) don't have a very good understanding of the other side in the argument, anyway.
Many evolutionists (particularly around someplace like here) will end up just saying what they learned in science class. Likewise, many Christians (again, particularly around someplace like here) will just say what they learned in church. An intelligent opinion can't easily be made without a good understanding of both sides. Anybody whose parents are evolutionists and who learns evolution in school will believe it. Anybody whose parents are Christians and who learns about Christianity in a church will believe it.
You are going to start out on whatever side you are raised with, it just works that way. I will say this though, I find way more evolutionists converting to Christianity than vice-versa. Does this prove anything? Not really, especially because the first thing that will come into many people's minds is "I guess the Christians do a better job brainwashing."
Bottom line: Learn both sides of the argument. Almost everybody who posted here gave me the impression that they really don't understand the other side of the argument, even if they think they do. A mind is like a parachute; it works best when it's open. And to anybody who has resorted to any kind of flame in this topic: don't try to pretend you have an open mind.
