      Scientists have a lot of evidence that points to the big bang happening but we don’t really know how it happened. We have evidence for what happened in the time after the big bang, but we only have theories about why it happened and what caused it.
      If you take a radio or TV and tune into a channel you can’t receive and hear static, a small fraction of that static is the noise of the big bang. Scientists can also detect it in other ways.
