What do you think of the theory that says that energy has always existed, and that it is possible that the universe expands until the force that causes the expansion becomes so weak that it then implodes and becomes the particle or whatever preceeded the Big bang, and then a big bang occurs again and the universe expands until..... and so on. ? ( I don't think I have expressed that very well, sorry)
The oscillating universe theory. As such, it's a theory with no empirical evidence to prove it.
Another question, for believers , or two really, first you cheerily say " nothing comes from nothing" then you claim that god made the universe from.... nothing ???
If God is, y'know, God, wouldn't he be able to do that? After all he doesn't exist in the natural universe and isn't constrained by the laws that exist in the universe he created. Is that as much of a leap of faith as believing that somehow living organisms developed from a biogenesis of non-living matter and that these organisms figured out they needed to acquire and utilise energy, acquire information and process that information, correct that information over time, pass on that information to its offspring, etc, and that from one single-celled organism all living things on the planet evolved of millions of years? Probably.
And this is important, if we concede, just for the fun of it, that an "outside" force or even personality brought about the Universe, how do you get from that to the God of the Bible ?
It's my opinion that Jesus Christ is the only religious figure who is claimed to be equal to God and is asserted in the Bible as being the image of - the revelation of - God. Jesus is identified in the Bible as the creator of the universe.
