Lumi you are taking these scientists too seriously, did you know that they just changed the age of the universe from 13 billion years to 26 billon years?
You have drawn an arbitary line between "supernatural" energy creation for what you belive in, then "thermodynamics" energy creation which is apparently impossible for what I belive in.
But here's the thing, I think that the energy always existed (it can just increase in entropy) so it's you violating the law with your big bang nonsense.
Comets with life travel between universes, it's just empty space inbetween. Each galaxy collapses back into it's core black hole, then the galaxies collapse back into each other then explode back out in a big crunch. Life survives by achieving escape velocity and being outside of the universal gravity bubble before it crunches.
Panspermia is the only thing that makes sense.
