First, people are aware of the fact that no god exists. Their private, personal behaviors often demonstrate their subconscious acknowledgment that no god is looking down upon them, watching their every move. Nevertheless, and for whatever reason, people argue against the atheist paradigm; they alleged that the non-existence of god cannot be proven.
Well, we can prove evolution. And, we can disprove the accuracy of the Bible and all other religious texts. So, if the Bible is not true and evolution did occur, there is absolutely no basis for the belief in their god.
Religiousites argue humans are the only creatures with eternal souls. Since people share a genetically demonstrable common origin with all other life on earth, when and where did that soul evolve? If trees and grass, mushrooms and toads, and all other forms of life do not have souls, then neither do their human relatives.
Once again: The Bible has been proven to be false. Evolution has been proven to be true. People recognize that no form of life has an eternal soul; and, the idea of a human soul is based on primitive magic, not on science. People are not a privileged creature that gets to live on forever and ever. Subsequently, there are no cosmic consequences to any human action.
Keeping things in perspective: There can be long-lasting affects as a result of human actions. These long-lasting affects can even include human extinction. Regardless of what each person does, there will be no eternal cosmic consequences; but the accumulated affects of what everyone is doing can affect the well being of the human species and all other life on earth.
