https://theconversation.com/usMany earlier thinkers had asked why our universe is the way it is, but Leibniz went a step further, wondering why there is a universe at all. The question is a challenging one because it seems perfectly possible that there might have been nothing whatsoever – no Earth, no stars, no galaxies, no universe. Leibniz even thought that nothing would have been “simpler and easier”. If nothing whatsoever had existed then no explanation would have been needed – not that there would have been anyone around to ask for an explanation, of course, but that’s a different matter.
And immediately we come to the, uh, heart of the matter? In contemplating the existence of something rather than nothing, what on earth does it mean to think of something as being "perfectly possible"? In fact the only way we can encompass this fully is in already having an explanation for why there
is something instead of nothing.
We have no capacity to yank ourselves up out of this particular something and examine it going all the way back to what may or may not have been the actual beginning of space and time.
We don't even know for certain if in coming up with words like "simpler and easier" we are able to do that as anything other than just another necessary component of space-time itself.
Leibniz thought that the fact that there is something and not nothing requires an explanation. The explanation he gave was that God wanted to create a universe – the best one possible – which makes God the simple reason that there is something rather than nothing.
In the years since Leibniz’s death, his great question has continued to exercise philosophers and scientists, though in an increasingly secular age it is not surprising that many have been wary of invoking God as the answer to it.
Of course an explanation is not required at all. We come into existence, we live out our life and then we die. Billions and billions of us so far. Some having invented God as the explanation, others refusing to.
Only in jettisoning God as the explanation, the answer becomes all that more mindboggling. God basically is the simple solution. No God though and somehow existence itself was either always around or had "burst" into existence out of nothing at all.
And how miserably unsatisfying are "explanations" like that?
