Often times I have heard people say that “Science has proven God”, or “Science is our way of proving God”. But how much credibility does this claim actually have?
None. None at all. Science is used to find natural explanations for why the Earth and universe is the way it is. Science makes no claim on the supernatural, and if God is outside of the universe (big step from living in the sky!) then there is no way Science can make any claim on his existence. Likewise Science can not ‘disprove’ God, we can disprove things about the Bible, like the creation story and the worldwide flood, but overall we cannot prove or disprove a divine being who is not in our universe.
Often times people try to put God into any part of Science that we don’t know, “God started the Big Bang”, or “God made Evolution work”. But this is the God of the gaps argument, and it is a logical fallacy. Using this approach, God is defined as a shrinking collection of our own ignorance. As we fill in the gaps of our knowledge we find no need for a God.
For the most part God himself cannot be proven to not exist, likewise we cannot prove Zeus does not exist, or the Flying Spaghetti Monster. But we know that something probably doesn’t exist if it is self contradictory, and that notion applies quite well to a being like a God, who is said to be omniscient, omnipotent, omnibenevolent and omnipresent. These terms not only bring up MANY contradictions among themselves, but they are also incompatible with the Bible and reality. It would be so much easier to believe in the Christian God if he was not this ultimate, incompatible being. Consider the claim that God is all-good and thus both perfectly merciful and perfectly just. If he is perfectly just, he makes sure that everyone gets exactly what’s coming to them. If he is perfectly merciful, he lets everyone off. But he can’t do both, so the notion of a supreme being may be internally inconsistent.
Overall Science itself cannot prove/disprove God, but philosophy and logic could easily make a being like God extremely unlikely to exist, and if it is unlikely that he exists then why bother believing in him?
