I will prove to you that God exists

[Sheldon]

Hypothesis such as multiverse or cosmic inflation are thought of as an explanation for an observed phenomenon. Of course even if the hypothesis is disproven, the observation that led to the hypothesis is still persists...why wouldn't it? I do agree that multiverse is a 'just so' time and chance naturalism in the gaps argument.

Nope the  multiverse is not a 'just so' time and chance naturalism in the gaps. There is no naturalism of the gaps it's valid hypothesis and if it's disproven all that happens is it's disproven and nothing else. This projecting the god of the gaps onto something that's nothing like it

Exactly, a scientific hypothesis is a starting point, and even if there is some evidence to support it, it is not an established or accepted scientific theory. this is just Drew' misunderstanding or misrepresenting how scientific ideas are validated. Another straw man as well...just as when he misrepresent what fine tuning means in the scientific sense, as "scientific evidence for a supernatural cause, and a deity," neither of which is true.
