i merely belive only 1 thing: in the beggining, there was intergalactic space, outside time and existence. sub-atomic particals were flying through space.
Nobody really knows what caused the Big Bang. If you do, please inform the Royal Swedish Academy of Sciences so that you may be awared the Nobel Prize in Physics. Also, I might be wrong, but seeing as spacetime was compacted into a singularity (a location where mass has zero volume and infinite density), how could these subatomic particles you speak of "fly through space" and "collide together"? Wouldn't that be impossible?
For the record: I completely agree with you that the Universe was created by the Big Bang and not by some invisible skygod for whom there is no evidence whatsoever. I'm an atheist and a passionate scientist.

How can a collision of essentially nothingness cause the creation of planets, stars and everything else in existence?
First: Essentially nothingness? Before the Big Bang, all the mass in the Universe was compacted into a singularity, which, as previously stated, had zero volume. But that doesn't mean that it was "essentially nothingness", it just means that it didn't have any volume in "conventional" three-dimensional space.
Anyway, after the expansion of spacetime (big bang) started (it has not stopped! The expansion of spacetime is still going on, and it's accelerating!), huge gas clouds formed in space for reasons
I don't know. Eventually, the densest parts of these clouds started collapsing due to the force of gravity. This caused huge spherical objects, called protostars, to form in the centres of these dense spots. The force of gravity caused mass to be drawn towards the centre of the protostar, until the release of potential energy caused the temperature of the star core to reach about 10mill. K. At this point, hydrogen in the core started fusioning to helium, and the gravitational collapse stopped because the forces created by this hydrogen fusion countered it. The star remains in this state for most of its life. That's how you get a regular star like the Sun. Planets are simply (I am not completely sure of this) protostars that didn't have enough mass to reach the required temperature to start hydrogen fusion. Fascinating stuff, eh?
I am no astrophysicist, so I can not guarantee that I've understood the Big Bang Theory and star formation 100%, but I am confident that I've understood the basic concept. Feel free to correct me if I've got anything wrong.

What a dumb excuse for a divorce. :/
Not neccesarily. Obviously, divorcing someone just because they are Christian, Muslim, Jewish or whatever is stupid, but if blacklumbob's father for example was trying to force his religion on him and his mother, I'd say that's a valid reason for a divorce.
