      Hi s1an1e,
      Yes, I do. There’s a lot of evidence for it in astronomy, and also from quantum physics. All the galaxies are still moving apart from that initial explosion, and we can still detect the energy that it created (called cosmic background radiation).

      Howver, I don’t think scientists really know what was there before the big bang, nor what caused it to happen.

      Hi s1an1e

      As James V said, I also think the Big Bang happened, and is also still happening (astronomers can measure that all the galaxies are still moving outwards and away from each other)
