Militant atheists of the Dawkins variety often raise the God of the gaps argument. They think the religious are just saying "Goddidit" for an unexplained phenomenon. Say like how Norse pagans used to think thunderstorms were due to Thor. But now that we know what causes thunderstorms, there's no need for Thor.
However, one problem with this point is it's a false dichotomy. At least when it comes to classical theism let alone Christianity.
For example, now that we know the scientific explanation for thunderstorms, does this mean we should no longer attribute the thunderstorm to God? Christians believe God is the one who made a planet with phenomena such as thunderstorms, that God made lightning as electrical discharge, indeed that God made the laws of physics from which such phenomena result.
In other words, positing God as the ultimate source of thunderstorms is perfectly consistent with understanding the scientific explanation for thunderstorms. It's not either/or but both/and.
It's like if scientists discovered a sophisticated alien spacecraft. After years of studying it, scientists have figured out how the alien spaceship works. They know how to turn it on, how to fly it, how to use its navigation and weapons systems, how to land it. They know how its engine and other internal mechanics work. They know its energy source for fuel. They know what material it is built out of. And so on. Basically, scientists know everything there is to know about the alien spacecraft.
But now that scientists understand all this, would it make any sense if they then said, "Welp, now that we understand everything about this spacecraft, no need to posit that it was built by an intelligent alien species, for that would be superfluous"?
Of course not. It's not inconsistent to say scientists understand everything there is to understand about an alien spacecraft and the alien spacecraft was possibly built by an intelligent alien species.
Similarly, it'd make no sense on Christianity to say now that we understand how phenomena like thunderstorms work, we can therefore abandon the idea of God.
(Besides, science itself doesn't always close gaps. Sometimes science in fact opens gaps as it closes gaps. Sciences brings more questions. Nothing unreasonable about that.)
