“Yes evolution is a religion of sorts.”
Just not one that meets any of the definitions of religion.
“It is a study of the ultimates, being where did we come from,”
Yes. But that’s not ‘ultimates.’ What we came from came from something else, which came from something else, which came from something else, and so on.
“what is our purpose,”
Evolution does not provide this, or even question it. We have to come up with that ourselves.
“what happens after we die,”
Again, not part of evolution.
"is there a reason for everything.”
That’s philosophy, not evolution.
“In these aspects, evolution is a religion”
Except these aren’t the aspects of evolution, except one.
“and by the idea of evolution and atheism, tens of millions of people have been murdered.”
Nope. Authoritarian tyrants have used atheism to avoid competition in controlling their people.
And killing based on ‘eugenics’ is not evolution.
“I find marxism a prime example of where atheism leads to, that and communism.”
The description of Jesus and his followers, sharing everything together, covering for each other, selling all they owned and donating the money to the group, is more communist than where my atheism leads me.
You’re just not batting a thousand on this topic, dude. Did you think this up yourself? Did you try bouncing it off of anyone who knows what Marxism is? Or religion?
