ah how does this other universe exist with excess gravity and why would it care to send just enough for us to live and evolve if that is your belief (If it had not happened that way; we'd not be asking the question. There is no NECESSITY for us to be here ya know. But, since we are here it is as a result of conditions of possibilty for us to be.)
remember to much gravity and things change to little and things changeas well. molicles don't form right black holes become to strong
the universe it self would of expaned right for life if gravity was not just so
earth's orbit and seasons would be totally diffrent and things for the start of life could not just suddenly happen in the proper sequence (Naturally we are very eager that we should exist. However, if other conditions had prevailed and a different sentient life form found itself gazing at that __other__set of conditions; it would marvel at how perfect everything was for itself).
If the universe is eternal; more than 99.99999999999999 per cent of its existence has been without us; thank you very much.
