Absolutely, it's quite a leap to say that a supreme being exists out there to the conclusion that Jesus was the son of this being, died resurrected, etc etc. It works for pretty much all the major world religions - it's not like comparing scientitific theories - religions are pretty much unfalsifiable, and choosing a single religion has to come down to a subjective preference.

Another common flawed argument is the argument from ignorance. Somebody that tries to convince you that science will never conclusively show either way if God exists. They move from that to say that since God hasn't been (and never will be) disproven, God must exist.

It's a terrible argument. "There are fundamental truths i'll never know about... and you'll never know about ie. God. Therefore, we both know that God exists." Admission of ignorance can never produce knowledge of anything.

Oh well, we make the necessary mistakes to learn stuff.
