My personal feeling ( which don't mean squat) is that anything material must come from a source.
OK, how do you define "material"? Does the source also have to be material? In this case, god would also have to be "material", which would completely contradict all religious concepts of a "spirit" being, with no end and no beginning. In any case, astrophysicists already have a very good understanding of what the basic building blocks of the universe would be, at the sub-atomic level.
"To say the universe has always existed with all it's material matter and having absolutely NOTHING before it is proposterous."
How is this any less preposterous than claiming some god-creature (for whose existence there is zero evidence) has simply always existed, and one day decided to "create" a universe, complete with a tiny little blue-green planet inhabited by organic, biological lifeforms? You basically have 2 choices here. 1) Either some "god" has always existed (because you are led down a road of infinite regression if you posit a "creator" for the "creator"; or 2) The necessary pre-requisites for a big bang event have always existed (e.g. subatomic particles within an infinite space). Now, given these options, we KNOW that sub-atomic particles exist. We can measure, and even observe their activity under the right conditions (e.g. heavy water neutrino refraction experiments). On the other hand we have no evidence for the existence of any god, beyond the wishful thinking of our emotions and fear of biological mortality. I honestly cannot comprehend how a logical person could be more satisfied with option 1.
