Abiogenesis is an extremely broad theory with multiple explanations for it, and as yet there is no single consensus on which one (if any) it might be. Some successful experiments have been conducted in a lab replicating the environmental conditions of the earth from when abiogenesis is thought to have begun, but to my knowledge that's the extent of it. The details of the big bang are also not settled, but it is known that the universe expanded from a single point -- that much is settled.IF these scientific theories (big bang and abiogenesis) could be proven beyond a reasonable doubt It would be one thing but considering that they cannot be proven I find it to be rather impolite that they are taught as if no other option is possible.
Religious people have an issue with matters of science they believe threaten their faith. That's not my problem and I can't help them with that.That's what most religious people have am issue with.
