  In my Masters research, I found out the age of the Moon (4470 million years old).
  
  We have no evidence of there being any other living creatures in space. However, the universe is huge and there are trillions of planets and stars out there, and many will be like the Earth. So I think there probably is life out there, we just haven’t seen it yet because it’s so far away.
