OK, tell me about the Utopias created in the name of Atheism?
Communism killed how many 100’s of millions? And brought what “good” to the world?
Yep, that’s a viable alternative.

There are no utopias. Never has been and never will be. Nevertheless...
Atheism is not a political system. Neither is it an economic system. It's not even a religion (did you know that certain flavors of Buddhism are atheistic?). What atheism is is simply
a lack of belief in god or gods, nothing more.

Communism does not equal Atheism. Communism was an
economic system (lousy and broken from start, but that's outside the scope of this post). While Communist dictatorships promoted atheism as part of their ideology, it does not follow that atheism was reason or even an important cause for their behaviour.
If there was comparison, we could talk about that edifying little episode called "
Thirty Years' War", all putatively in name of christianity. It may have not killed hundreds of millions, but there were not enough population for that in those days. Excess mortality from that little conflict is estimated to be 15-20% of the entire population. If the population had been comparable to today, we wouldn't be talking about megadeaths. We would be talking about
gigadeaths...
