Re: Alien UFO's are Real - True / False...
You are confused about what 'believing in the big bang' entails. What it entails is believing two things: firstly the universe was, long ago, much hotter and denser than it is now, and secondly that the density & temperature increased very rapidly & without apparent bound as we go further back towards some limiting time. Both of these beliefs are strongly justified both by experimental evidence and by our theoretical model of the evolution of the universe. There is nothing inconsistent about these beliefs.
What we definitely don't understand is the 'without bound' bit: as the density and temperature increase we know that we do not have theories which work any more. So we can predict things backwards only to the point where the theories we have fail: beyond that point we must wait for a theory which works.
In particular any talk about 'quantum fluctuations' giving rise to the universe is just speculation: we don't have a theory that works at that point and so there is not very much we can usefully say.
