      Hey Grace,

      I do believe in the big bang theory. I think it’s the theory that scientists have the most evidence for – lots of predictions from the theory have been observed by scientists on earth, which I think makes it sound correct.
      One brilliant fact is that scientists predicted that the big bang would have an echo and what it would look like. Meanwhile scientists elsewhere had already found the echo, but didn’t know what it was. Eventually the two groups put their work together and the big bang theory gained a lot of support.
      This is what they saw:
      And here are some great short videos that might explain more, enjoy:

      Although there is loads of evidence for the big bang theory, it is still called a theory because we still haven’t proven it for sure.

      Nicholas nicely points out some of the evidence for the big bag but here’s a nice infographic on other theories instead of the big bang theory and these can’t be ruled out until each of them have been disproved. http://www.space.com/24781-big-bang-theory-alternatives-infographic.html
