Question
Is there a connection between life on Earth and life on other planets?
So far we have not discovered life on any other planets. If and when we do discover alien life, the possible relationships with life on Earth will be of prime scientific importance, such as whether such alien life uses genetic molecules like RNA and DNA. David Morrison
