You claim the following -" Take a rock(earth), place it near a heat source(sun) and in a vacuum(space) and come back to it in 10 billion years. You will still have a rock near a heat source. There will be no life on board, no mini humans on it. Better scientists than me have proven that."
1. Are you a scientist?
2. What scientists better than you have proven that, and please provide a link.... See, no scientist that I am aware of has had 10 billion years to leave the experiment and then come back and observe.
It has been shown, by, amongst others, Miller and Urey, that the conditions on an early earth actually favoured synthesis of organic compounds from inorganic precursors - this being hypothesised by Haldane, amongst others. So I think your assertion, above, seems comprehensively contradicted by their work
You also had this to say - "I believe in the theory of evolution and i belive that earth evolved over billions of years. I do not believe that we are here because of just circumstances". - Now this is great, I agree with you on 2 out 3 of your statements. Why, do you think, should we attach any weight to your 3rd statement? Just because you do not believe that we are here because of "just circumstances" does not mean that it is not true. What you have with that statement is a logical fallacy, an argument from personal incredulity.
You are also very probably correct to hypothesise that, given the staggeringly huge number of galaxies, each containing a massive number of stars, a significant proportion of which will have planets, there is almost certainly life out there in the universe - but although we can speculate that there is intelligent life more advanced than ourselves, it isnt necessarily so. As to advertising ourselves, well, yes we have been, but only for a relatively short time, since the use of radio waves, TV signals and the like, and they will not have got very far, especially in comparison to the size of the universe.
Finally - the theory of origin, the Big Bang. It is a hypothesis, and one that is the best fit to describe the beginnings, based upon what we know. There are bound to be refinements to it, but your analogy is like many, that the big bang was an explosion akin to something we can see on Earth, when of course it is absolutely nothing like that. The theory posits a singularity, which are just plain weird. The alternative, religiously inspired theory, that there was some sort of supernatural cosmic entity that created everything seems much less plausible, and would appear to me to be there as a means of satisfying humanities deep seated need for a narrative.
