You didn’t explain what I asked. Where did the material that exploded come from, and if there was no space what was there? You can’t have an explosion that creates matter, you can only scatter it with the explosion, and sometimes you turn matter into energy when it explodes, such as in a nuclear explosion. I would imagine the “big bang”(which I don’t subscribe to, BTW)would have many orders of magnitude above any nuke explosion we have ever witnessed. Nope, your little rambling comment explains nothing. Nothing I have ever read answers the question: Where did the original matter come from?
You have to take things by steps. The first step was taken by Einstein, who conceived of space-time. Lucretius makes a comment prescient of this, "Time also exists not of itself, but from things themselves is derived the sense of what has been done in the past". Remarkable.
With General Relativity, Einstein established what Wheeler calls Geometrodynamics, that is a physics OF space-time, rather than a physics that transpires IN a rigid framework of space-time. But the idea of an evolving or changing space-time begs the question of time. It seems to require a "time out of time". This is thinking at the limit of what it is possible to conceive.
Proponents of the big bang say that it all began with a singularity, which isn't an object but a horizon.
When the temperature is a billion billion billion degrees, all four fundamental forces are melted down into one substance. When it explodes and cools, time-space geometry, mater and chemical compounds emerge.
Seems like the physicists have mathematical formula and other good evidence for all of this and it jives with basic theology.
But, you say that you don't believe in the big bang.
Why do you doubt it I wonder. So, you are a creationist?
