1. Its a theory, its not a fact
2. There are plenty of scientist that don't believe in the Big Bang
3. If it wasn't a big explosion, which by the way a "Bang" is, why isn't it called the Big Expansion?
4. I am fully aware that there are billions of planets and stars, I own a telescope and love to look around in space.
5. I wasn't just comparing it with man-made explosions, I also mentioned nature explosions, such as volcanoes, solar bursts, etc.
Okay I'm going to respond to all these points somewhat briefly.
1. Once again it is clear you know very little about the topic. The word theory has a different meaning in the scientific world. Science doesn't claim to offer absolute proofs and is constantly adapting when new discoveries are made, something religion mostly fails to do. This allows all theories to be open to debate, which is a good thing. However some theories are essentially proofs (but not quite), when there is so much evidence supporting it. The Big Bang is one example of this. Here is some of the evidence, just google it and maybe finally do some research for once.
- Abundance of Hydrogen/ Helium in the Universe
- Cosmic Background radiation
- The doppler effect
I hope you know that gravity is also still a theory along with the Big Bang, yet I don't see you criticising it.
2. You're wrong when you say plenty of scientists don't believe in the Big Bang. 99.9% of scientists related to astronomy believe and support Big Bang theory. So thankfully you and your silly opinion is in the minority.
3. The name is misleading, the term Big Bang came from a scientist called Fred Hoyle and the name just stuck. The Big Bang was not an explosion as it had no centre.
4. So if your fully aware that there are billions of planets, how on earth do you not understand that the probability of just one of those planets supporting life is massive, it is ludicrous to suggest the alternate.
5. A VOLCANIC ERUPTION IS NOT EXACTLY AN EXPLOSION. Also this point is completely irrelevant as the Big Bang as I said previously was not even an explosion.
So in conclusion, once again do some reading before debating on this topic and please google that little list I gave you.
