Evolution is probably real, so that's why I believe in it.

Think about it - unless you're an idiot and actually believe the fairy tale that is Genesis (or any other 'creation story' where humans were created in their current form), when life first began to roam the Earth, the world was very much uncivilised - while it is somewhat plausible to believe that mankind began existence 'as is' i.e. how we are now, it is not plausible to believe that the technology that we rely on to survive, such as vaccines, weaponry and heating, existed with us. Look at humanity in its current form - we're weak, cowardly, selfish beings with nought but pink hairless monkey suits and a very vulnerable immune system. Back when the world was uncivilised and roaming with large, hairy, feral beasts with big teeth and disease was far more widespread, humanity as it exists today simply would have not survived.

This isn't evidence for evolution itself per se, but since carbon dating for the planet itself goes millions of years back, whereas human civilisation can barely be backdated 10 000 years, it would be foolish to deny that this is the truth.

Also, evolution does not contradict the existence of God - it merely contradicts Genesis. Both Genesis and Evolution were devised by a man, or men, so saying that one carries weight over the other due to its author is outrageous.
