Because if I were, I'd have to believe unmitigated BS.
Like the universe is the product of chance.
So reason, if it exists, comes from unreason. Again, strict logical necessity here. The universe is irrational from the beginning. We are not from the beginning by any account of things, so our ‘reason’ comes out of unreason. Reason, far from being supreme, is an accidental byproduct of unreason.
Anyhow. Now the atheist materialist may counter with, essentially, “Yeah, and so what?” The universe is meaningless, you’re meaningless, I’m meaningless. It’s an ugly picture, but that’s reality.”
They argue that religion causes violence (which is laughable), but if meaninglessness is king, then what’s wrong with violence? Bears are violent, and so are wolves—why not us? Cows eat grass, humans kill one another in wars. If the universe is, as they claim, vacant of any ‘law,’ what’s the problem?
Now, some may respond: oh, it's the atheists-are-immoral meme again.
Some atheists are practical people who understand that human nature is fixed and that the predictable nature of human behaviour makes moral law possible.
I'm not saying many believe this, just some.
However, they do not connect the dots between their belief that God does not exist and the existence of reason, order and morality in the world.
If there is reason, order and morality in the world, atheists expect us to believe it's all a product of chance. That a great cosmic chain of event pushed some atoms to all come together and produce what we know as human beings and wisdom that we know today.
If that is not the biggest intellectual fraud around, I don't know what is.
