Critics of evolution have often rightfully observed how the idea of humans coming to exist by chance is utterly ludicrous, and actually mathematically impossible. Anyone can see just by looking about that this couldn't have happened by chance... the odds against this world coming about by chance are essentially infinite. Here's a simple mathematical disproof of evolution: As a conservative estimate, lets say that historically 10% of people have been childless. Considering the rate of infant mortality and young deaths, the actual percentage may be considerably higher. Now let's consider how many ancestors you've had. You have 2 parents, 4 grandparents, 8 great-grandparents, 16 great-great-grandparents, etc. This grows at such a fast rate that when you go back 20 generations (which would be maybe 1000 years max?) you'd have had a total of over two million ancestors. Evolution requires genetic material to be passed on from parents to children. Thus, the totality of evolution rests on the (insane) claim that all of our ancestors had children. Think for a moment about how insane that claim is... in every generation, all the way back, every last one of your ancestors has to have had children according to evolution. Simple probability says that even if you only take the last 20 generations into account, 200,000 of your ancestors (10% of the two million) should have been childless. Math tells you 200,000 and evolution tells you 0. That discrepancy is far, far beyond the range of what anyone could claim to be random chance. Thus, evolution is mathematically false.
