How do we tell right from wrong?

Stop right there, see that’s where you went wrong.I'll make it simple
Evolution has nothing to do with morals (full stop)So therefore let’s look at it from the opposite angleIf we need religion tell us what’s right and wrong
v
Then we are only performing right and wrong based out of fear from devine judgment, therefore hell.
v
Therefore it’s not out of our own judgment that we perform actions of say good, it’s because of this installed FEAR of hell.
v
Thus a Atheist with no belief in any deity can actually be more moral then a religious person due to the fact, that if he performs good, then he’s doing good out of his own good will. Not out of fear of performing wrong in gods eyes, thus getting cast into fiery pits of hell.So really who’s the more moral person?1) The guy doing good because of divine retribution and thus fear
2) The guy doing good because he wants to perform good actions. He is doing this out of goodwill, not installed fear.So maybe if you wanted to actually attack the non-believing heathens such as myself you should sayIf deities are false, shouldn’t we all do what we please, evidently society would collapse if this happened, and funnily enough it hasn’t.PS: Australia my homeland has many religions and many atheist and we are still here!
