This question is mostly to people who lack the belief in God (Mono).
Let's put aside for a second the term God and all the ways people try and define this god.
Would you agree that there must be an initial cause to everything?
I mean that from our human POV, we today know that time had a starting point, this means that (from our POV) there was a point in our history when time "stood still". We can refer to this idea as an eternity (again, only from our POV as we don't really know what happened before that).
Also, there has to be an event (or something else
) that started the whole process of reality. even if you somehow believe that reality started itself, this means that some sort of "reality version" existed before our reality, we can refer to this as the initial state of existence.
This means that eventually, going back chronically (events wise), there must be an initiator (regardless of what that initiator is) that was there without being initiated in the first place.
So we can assume regardless of our belief that there was an initial event that was "placed" in what we can only describe as eternity as we have no understanding of time before our time.
We can also have the understanding that this thing, contained within it all our reality, meaning the universe as we know it emerged from that same initiator causing our reality to become what it is.
Thoughts?
