Atheism is unreasonable

[Esquilax]

"Real science" is supposed to be based on observation and repeated experiment...yet you believe in a theory that is unobserved, and can't be experimentally validated...and I am the one who refuses to acknowledge real science?

As I keep telling you, and you keep ignoring like the intellectual derelict you are, "observation" in the case of science does not necessarily mean "live direct observation right in front of your eyes." That helps, and in the case of evolution we actually have that, but the observations science uses can also be observations of the evidence that leads to certain conclusions. In the case of evolution, we observe the way genes behave, the way the fossil record is arranged, the way animal morphology works, and when we couple that with the direct observation of speciation we have, we can deduce the nature of evolution and common ancestry. This kind of deduction is the only way we can ever know anything about the past, for example, or things in the future, like Pluto's orbital period, that I've mentioned before. I know from conversations that we've had in the past that you're happy to accept the efficacy of this kind of deductive conclusion when you think it confirms the existence of Jesus, meaning that the fact that you're dismissing it now when it can be used to come to a discovery that you don't want to be true makes this yet another double standard on your part.

Now, again: what is the mechanism that would prevent genetic differences from accumulating in organisms over time to the point that their offspring transcend species barriers?
