Your faith in science is misplaced scientific study doesn't provide a logical reason why maximum pressure rise and mechanical leverage ALWAYS happens at 14 degrees after top dead center in an internal combustion engine regardless if it's rotary or reciprocating. There is NO explanation or theory that can explain why. Natural selection is not obvious, an ecosystem is a complex web of variables, what works in one instance may not work in another. Natural selection is too slow a process to explain the adaptability of different sub species of the same animal. Real reality is too far beyond your perception, but by indulging atheism you can claim to have all the answers, despite overwhelming evidence to the contrary. This is not to say that one should not even try because the reality is too far beyond you. No, I'm not saying that at all, the universe gives us every opportunity to discover its mysteries and it's given us the tools to try to make sense of all this. It is an imperfect process full of mistakes and errors, and in that process you slowly increase the resolution of the truth. This is growth, this is what drives us, therefore it is correct. It is a journey, the atheist only sees the destination.
