Notice the difference between assumptions and divine revelation.

(quote from RealReality.org/Real_Faith_and_Reason_Vol_2_-_Scientia.pdf)

Even though we can’t base assumptions on previous experiences directly, we assume carefully. Our assumptions don’t conflict with something real in a way that’s obvious. Not usually. Our assumptions conform to what anyone can easily check. Here’s the problem. Assumptions also conform to worldviews. And worldviews seem real. Hardened worldviews even seem more real than what we can easily observe. These are Satan’s strongholds in our minds.

Therefore, we must concede that people don’t always assume in a vacuum or in a way we can easily prove false. However, just because we make assumptions that don’t conflict with observations, Scripture, or experiences in an obvious way, that doesn’t mean the assumptions have somehow become true.

What God says is true. Assumptions consist of made-up stuff. When someone says the Big Bang Cosmology is fact, it’s OK to see if other cosmologies explain the observations as well or better. Those other cosmologies that work better expose the dogmatism of false science that insists on the Big Bang Cosmology. The danger is in thinking any cosmology is based on more than vapor. None of them can be proven. We can only prove they don’t conflict with what we observe or what God reveals. They are all laden with assumptions. There’s a vast gulf between assumptions and reality.
