so my "Big Collide" theory is explaining what caused the "Big Bang" to happen and this is how I describe my theory so, nothing never existed,nothing never leads to something,so, the universe was just filled with matter and antimatter, and one day, they collided, and the matter and antimatter annihilated,which created radiation,and caused a blast force of 2000000000000000 nuclear bombs going off at the same time,which was the big bang, all this destruction slowed down after a while, and the universe cooled down, and then, dark matter showed up, the old antimatter and matter that exploded turned into tiny pieces of quarks and leptons,which combined and made neutrons and electrons,which later turned into hydrogen,oxygen,and iron.
