Our universe is pretty simple. It either was created or it came from nothing and will end in nothing. Our senses detect something, rather than nothing, so it seems more likely that the something was created. Even when we die, we don’t disappear. We decompose and return to the recycling bin. Death probably does not lead to nothingness.
Nothing is a very negative concept. Nihilists and other pessimistic philosophers may believe in nothing, but their beliefs are something itself. Any thinking or activity or even inactivity is something. Even a rock, an inanimate object, is something. Nature abhors a vacuum. Even outer space which appears to be empty has neutrinos and other small objects scurrying around.
Try to get past all the evangelical and fundamentalist preachings about God and define Him to be the Creator and Designer of the universe. God is that catalyst who brought matter and energy into our universe from an outside world. For you see, matter and energy can neither be created nor destroyed in our universe. So God has to be outside our closed universe. And since God is something, our universe did not come from nothing. I have no clue where God came from, but perhaps we will find out after we die.
It is interesting to speculate about spontaneous generation. But something coming from nothing is not a very strong theory. Everything that we know about in our universe works in cycles. Even the Big Bang could easily bounce back and forth with a Big Crunch. Electrons orbit the nucleus. Our earth orbits the sun. Everything seems to have design instead of nothingness. Everything appears to have meaning instead of chaos. That is not to say that there is no chaos in the universe. There is chaos, but the chaos even has design and fits within the system. But I don’t know of any matter and energy being produced from nothing within our universe.
Thus, we either go with the concept of God, the Creator, or nothing. Not much of a choice for me. And the real clincher is that there is no downside in picking God over nothing. But there is a downside if you select nothing over God. An unhappy Creator can send you anywhere He wants, and there are a lot of bad places in the universe.
