We can do that because, in the view of evolution, the conditions for evolution have been just right. If they were any other conditions, we'd have turned out vastly different and may not even have lived this far.

I believe this because I've seen and known too much about how the world works and how different things happen to believe otherwise.

I think you're referring to the anthropic principle, which has different variations. Proponents of "intelligent design" have argued: given the extreme unlikelihood of the finely tuned constants of the universe being conducive to intelligent life, when selected at random from the ranges which they could have taken (think of universe generation as a repeatable trial), it is extremely unlikely that the universe "randomly" resulted in intelligent life without the intervention of an intelligent designer (which would imply a supernatural God).

Reading up on it a month or two ago, I found an interesting and compelling argument that the weak version of the anthropic principle (as defined in the Wikipedia article as "The observed values of all physical and cosmological quantities are not equally probable but they take on values restricted by the requirement that there exist sites where carbon-based life can evolve and by the requirements that the Universe be old enough for it to have already done so") actually undermines the intelligent design conjecture. It can be difficult to follow, though, if you haven't had much experience in mathematical probability proofs. Follow the "it has been argued" link from the Wikipedia article to get to the page I'm referring to.
