is the big bang theory real

First of all, Big Bang didn't come from nothing; it comes from an extremely dense and hot singularity, said singularity is the source of all the energy and mass. As for what's before the singularity turned into the Big Bang, no one really knows. It could've been another universe dying or anything, even God, just that God is one of the least probable answer with absolutely zero evidence for it. Just because we don't know something yet doesn't mean it is God. And like I said before, there is a possibility that the Big Bang isn't really what happened, but all the data we gathered provide evidence for that theory and there is no solid counter evidence against it; As for God being responsible, there is none. Yes I know life is complex, but that doesn't mean it can't be created randomly. For the sake of argument, lets just say the chance that a planet that is suitable for life and there being a random chemical boil that creates life is one in a trillion trillion. With the amount of planets in the universe, and the possibility of there being multiverses, the chance isn't actually that small that at least one planet has life. And even with the right conditions this planet took billions of years to develop the first life. There is actually an overwhelming amount of evidence that is against what the bible said about God creating the world in seven days. However, people just defend it by saying that the days in the bible is not 24 hours but we all know the people who wrote the bible long ago meant it literally. The statement that God has always existed is just a convenient answer to the question of "Where did God come from?" Since your God is omnipotent, you can use any answer to justify it's existence. Just because something is convenient doesn't mean it's correct. It can be a 5 feet tall fairy that created this universe or even some aliens, it has the same amount of evidence toward them as there being an intelligent creator. You keep saying that God is the only explanation for a complex universe but there wouldn't be any observers to observe a "bland" universe that cannot sustain life. The only reason we can even observe this universe is because it is complex. Who knows? The universe could be an unending cycle of death and rebirth. We just don't know enough yet. You still have yet to provide any evidence that God exist besides a literature written by humans. Basically your only argument for God creating this universe is that you don't understand how the universe came from the singularity, so you go for the simple and easy to understand explanation that is an omnipotent God. It is the same as when people back then believing that Zeus is responsible for lightning. There is literally no difference. Point is, the human mind may not be equipped to fully understand everything, and every scientific discovery only lead to more questions. All religious people do is push God into the unknown, claiming he is responsible for it. I suggest that you do more research on the Big Bang theory and how we came to that conclusion with years of collected data and remember that just because we don't have an explanation on something yet, it doesn't automatically means God.
