Consider the beliefs of evolution/atheism, also known as “Darwinism:"
I have - probably moreso than you. Why do people who do not understand evolution conflate it with atheism? They aren't the same at all.
There is no right, wrong, good or evil. If you kill 153 people and nobody finds out, what makes it wrong?
If you don't understand why killing 153 people is wrong, then how is your Christianity better than my atheism?
Everything that exists is a random collection of chemicals with no purpose.
Well, no. Random is not the same thing as chaotic by a long stretch. But things don't have to have a purpose in order to exist; to reason otherwise is the naturalistic fallacy.
Why help anyone else with anything?
Again, if you don't understand why, I don't see how you can tell people your Christianity is better than my atheism. But, indeed, why? We atheists are capable of understanding the concept of grace, you know.
Survival of the fittest rules the day.
How is a true statement proof of an incorrect conception?
Horde all the material possessions you can for yourself, because that’s all there is.
Atheism is not a form of materialism, just as "Darwinism" is not a form of atheism. Materialism results from feelings of inadequacy or fear, not lack of belief in God.
Love does not exist, just chemical reactions that are a result of randomness.
Please stop conflating "existence" with "reality". True, love does not exist, as it does not have a physical form. However, love is real because we feel it and it has an effect. And again, nothing is truly random, either. Chaos and randomness are not the same thing.
