String theory and multiverse theories are BS of the worst sort, motivated by a recognition of the mathematical odds against evolution in the one universe which we actually live in and know anything about.
String theory came about by accident when two physicists accidentally discovered that an obscure eighteenth century mathematical expression called the Euler Beta function unexpectedly described quantum behavior. There was no anti-relgious motivation involved at all.
Point to ponder...
The other day someone posted an interactive site zooming from the smallest parts of what we believe exists, through the mwasureable, up to the spherical ball that consists of the believed universe...
It went like this...
Bits of point matter
Empty space
Bigger bits
Empty space
repeated a few times
Then...
Bits of matter (quarks and such
Empty space
Atoms - Bits of matter orbited by other bits of matter
Empty space
Bigger ones
Empty space
repeated a few times
Then...
Things we can see with microscopes
Things in the world
The World
The Sun
solar system (Matter with things orbiting around it)
Empty space
Other solar systems (Matter with things orbiting around it)
Empty space
Our galaxy (central core with things orbiting around it)
Empty space
Galactic clusters (central core with things orbiting around it)
ETC
Zoomed out far enough, our universe appears to be a point of matter.
So considering the repeating process above, The fact that we could be one ‘molecule’, our universe could be one molecule in a much larger ‘thing’, with uncounted others, does not strike me as far fetched.
Anyone thinking that in a couple hundred years of actual hard science, that we have done anything but scratch the surface of what ‘is’ in ‘reality’ is pretty arrogant or deluding themselves. One of the two.
With a 100 billion galaxies each with a 100 billion stars, why would anyone think the odds are against evolution appearing even once?
We have discovered complex organic molecules in space. To think life hasn’t formed at least once in 13 billion years seems farfetched.
