The possibility exists that everything I've been told is a lie. However, some of what I've been told is certainly verifiable. For instance, much of physics, especially classical physics, is self-verifiable. Heredity is also, for all practical purposes, verifiable. Genetic variation from parent to child is also verifiable. Many, many more observations are verifiable. These all coincide with the phenomenon of evolution. The same can not be said about most major religions.

Secondly, the reason I trust what is considered scientific fact is not because I have some unyielding trust in people, it's because every experiment they perform is verifiable. The theory of evolution can not be a conspiracy because it is simply far too massive of a conspiracy to not leak. There are many, many social checks and balances in the scientific community, which is why I trust scientific fact. Religion, being based on faith, does not have these checks and balances.

BWAHAHAHA! Believe that if you want. Do you know what a scientist would get for hard evidence against evolution? The Nobel Prize at the very least.
