Do you agree that something cause things that do not exist to come into being?
I don’t know; can you give an example of this happening outside of your theistic beliefs?I don’t know if I can agree with that. Life is when part of a man and part of a woman come together and evolve into another man or woman. So though there was not a time when the parts were not alive, I guess there is a point when the parts become a person/being.PaulSacramento wrote: ↑Wed Feb 20, 2019 9:42 amLife.
Life does NOT exist until something causes it to come into being, yes?Perhaps I’ve misunderstood you. When you said acting outside of themselves, I thought you meant something outside the material world. If you meant “X” acting upon “Y” with them both being material; that would make sense to me.No. Energy is not matter, though it is a part of the material world.
Please define "material world".
So, here is the thing, we tend to use the term universe to mean everything BUT if the universe had a beginning, an expansion, from a quantum singularity, what was "around" that singularity ?
The universe is still expanding, but "into" what" or "where"? and where is the energy coming from to continue the CONSTANT and CONTINUOUS ( albeit quicker) rate of expansion ?
If the energy that exists has always existed and will always exist and is/was/will be always the same, why and HOW the expansion?
