hi,my name is uday and I say no gravity was existed before the big bang
Therewas nothing, not even time, before the big bang. The very start of the big bang remains unclear, but after a little while when the universe was still small there was certainly an effect from gravity, but likely small compared to the other fundamental forces, which are many orders of magnitude larger (and which don't quite cancel considering the plasma state of matter).
huh?
It's not - the big bang theory is related to the creation of the Universe, AI is related to human thought.
Largely by being not related. The Big Bang theory doesn't really say anything at all about gravity.It's kind of distantly related through the "Theory of Everything", but the problem with this is that there is no Theory of Everything yet (actually, the situation is worse; there are multiple Theories of Everything, and we have no idea which is correct, or indeed if any of them are).
That depends by what level of "stick together" you are talking about. For example, quarks and gluons combined to form protons and neutrons, approximately one millionth of a second after the Big Bang. For other levels of "sticking together", check the Wikipedia article on the Big Bang.
Yes, ever since the Big Bang at least.
No, the Big Bang was not an asteroid. The Big Bang theory is the scientific explanation for the origin of the universe, proposing that it began as a singularity and has been expanding ever since. An asteroid is a rocky object in space that orbits the Sun, and is not related to the concept of the Big Bang.
Weight is a function of gravity. Gravity is determined by proximity to mass. At the point of the big bang, all the mass of the universe (which is said to be infinite) was compressed to a single point. Therefore the pull of gravity, and thus the weight of that mass would also be infinite.
Gravity. Note that mostly it wasn't all that dense.
Unfortunately I did not. See related questions.

Gravity is the primary force involved in the formation of galaxies after the big bang. Over time, the gravitational attraction between matter caused it to clump together, forming structures like galaxies and clusters of galaxies.
