"The scientific concensus is that approximatle 14 billion years ago, reality (time,space, laws of physics) sprang into existence."
The Big Bang theory is about the universe's development over time. The big bang, is still banging; we're still expanding. It is not about the origin of the stuff, at the beginning of the universe.
"Now, this in itself contradicts the first law of thermodynamics, matter cannot be created nor destroyed unded NATURAL circumstances."
From quantum field theory, we've seen electrons, positrons, and photons effectively appear out of nowhere. They do not violate the conservation laws of physics. Indeed, in the crazy world of quantum mechanics, something can come from nothing.
We do not know if the laws of thermodynamics were even applicable to "before" the big bang. Additionally, we do not know if anything could've even "caused" the big bang, as causation requires time, and time is a result of the big bang.
"Therefore, something supernatural would have caused the creation of matter."
It's a huge leap to go from "supernatural" to "the Christian god"
"But isn't the idea that matter and space created themselves out of nothing, (not even time or a vacuum) even more unbelievable?"
We don't know what "caused" the big bang, and if that's even a valid question.
We have to ask, where did God come from? If God can be excused from the rules, why can't the universe? Why the most complex creative entity ever, not require a creator?
"There is a line in the Bible that says God created the universe and stretched it out. Stretch? the universe has been expanding , long before science even realized it, but the Bible stated it."
The Bible also talks about a mountain and tree so tall, you could see all parts of the Earth.
Okay, now onto why I don't think the Big Bang complements Christian theology.
Humans are, according to Christian theology, special, yes? The universe seems to be made with just us in mind. So why'd God wait 9+ billion years to make our planet? Why this large, ever expanding universe when we only occupy this pale blue dot? Why did modern humans only appear ~200,000 years ago?
Those simply does not seem like the actions of a being that created all this for us.
Edit: "It was a christian priest who came up with the big bang"
That's an appeal to authority. I don't care who believed in something, I care why they believed it.
Edit 2: "LIFE CAN"T ARISE from nonliving things, EXCEPT of course for the one time it just happened to."
Ah, so we've drifted to abiogenesis. Fun. The formation of the first self-replicating strand of genetic material did not "just happen".
When you drop a ball, it doesn't "just happen" to fall towards the center of the Earth, gravity acts on it. Much in the same way, the amino acids did not randomly combine, but forces at work on the chemical level caused them to.
