@chai2,
"As far as I'm aware, scientists don't say something came from nothing either"
O yes yes yes they do!
"“Hawking said: ‘Because there is a law such as gravity, the Universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the Universe exists, why we exist…’"
And another one:
"One theory is that the universe came from nothing. i.e. perhaps bubble-universes collided, as in a bubble bath, and gave birth to the universe. Or perhaps the big bang was created by a bubble-universe which split into two universes. The universe does seem to be compatible with nothing.
Michio Kaku"
And another one:
"The fact that life evolved out of nearly nothing, some 10 billion years after the universe evolved out of literally nothing, is a fact so staggering that I would be mad to attempt words to do it justice.
Richard Dawkins"
And another one:
"A universe that came from nothing in the big bang will disappear into nothing at the big crunch. Its glorious few zillion years of existence not even a memory.
Paul Davies"
"This “quantum cosmology” provides a loophole for the universe to, so to speak, spring into existence from nothing, without violating any laws of physics.
Paul Davies"
"The universe can spontaneously create itself out of nothing
Stephen Hawking"
And on and on it goes..
Quit some jokers eh?!
