God is actually the ultimate truth. Knowing that truth is the salvation. Every religion and to some extent science are ways of trying to know that truth. For science, God is an ultimate equation, that clearly explains the existence of universe.
Even with long headstart the religion got in understanding the truth, it faltered somewhere down the line due to lack of flexibility to adopt to changing views and new truths. Science is now leading that path to salvation, with all its weaknesses.
Once we get to know that truth, then we will become GOD.
