THE THEORY HAS AND IS STILL CHALLENGED. Holy crap, do you think once Darwin wrote it down and dug up some rocks they just went, "Shit we solved it, pack it up we're done here for all eternity"? Nobody is saying believe it 100%, I'm telling you it's the best we have so believing it now is smart because there is no contesting theory, but believing something doesn't mean giving it your all. If it's not the best, then what is? You claim things and do not back them up, how researched in the subject even are you? You say the fossil record is all the theory has for support, have you learned how that's wrong yet? Research it before saying things like this.
