Evolution has been proven to be true for starters. True, potassium-argon dating is assumed to be true based on scientific observations for objects ranging from 4.3 billion years of age to approx. 100,000 years of age providing they have not been heated to the point of recrystallization at a later date. So, there is still much we do not know and we use multiple methods to figure out the age of something or to confirm the age. According to the bible however, the earth is only 6,000 years old. So, if we are going to believe the bible then we must discount every dating method that shows the earth is over 6,000 years old.

However, if we are going to accept that mountains of evidence for evolution exist and evolution has been proven to be true based on its reproducibility and mountains of evidence and at least some of these dating methods are somewhat accurate... based again on evidence and facts collected then we can begin to look at other creation stories... which incidentally do not agree with each other either.
In the beginning of time, there was nothing: neither sand, nor sea, nor cool waves. Neither the heaven nor earth existed. Instead, long before the earth was made, Niflheim was made, and in it a spring gave rise to twelve rivers. To the south was Muspell, a region of heat and brightness guarded by Surt, a giant who carried a flaming sword. To the north was frigid Ginnungagap, where the rivers froze and all was ice. Where the sparks and warm winds of Muspell reached the south side of frigid Ginnungagap, the ice thawed and dripped, and from the drips thickened and formed the shape of a man. His name was Ymir, the first of and ancestor of the frost-giants.
And while it may always be true that there will be unanswered questions as knew knowledge gives rise to new questions, I will side with that which has some proofs, evidence, facts, observable details... and leave the rest to those with the ability to believe in things without proofs, facts, or evidence. I personally will not simply believe that magic is the answer until magic is proven to exist. I personally will not believe in unicorns, dragons, santa, gods, goddesses, demons, or anything else that fits the bill of being called a myth or religion as I do not need myths or religions to complete me. I am whole and I am just fine without these things and I could not see a god who if he/she existed would need be to believe in him/her. I anthropomorphize god concepts enough, as many cultures have, to think him/her above such petty needs as needing us to believe in him/her for him/her to treat his children kindly regardless of their differing beliefs in him/her or even the absence of belief altogether. I do look at gods whether they be Zeus, Horus, Allah, Mythra, Inyan, Iktomi, Mythra, Odin, PachaMama, or any other cultures gods to be on equal footing with not only each other, but also unicorns, dragons, imps, demons, fairies, etc... as far as proof of existence goes and I fully realize that many do believe that each and every one of these beings does in fact exist. I fully realize that many people believe religious doctrines that go directly against another cultures religious belief and that most cultures thinks they have the correct doctrine... the correct beliefs... the correct relationship with their gods. Blind belief and feelings however does not prove one god or belief system to be any more valid anymore than a holy crusade, witch hunt, or any other event can confer real validity upon a belief system.
