  1. There are chemical signatures that possibly indicate life of some kind on both Mars and Titan. We have already discovered several planets scientists believe are better for development of life than Earth. String theory? Get a pot of coffee, we will be up all night on this subject.

  2. First great extinction is when single cell life discovered photosynthesis with chlorophyll and produced scads of "poisonous" oxygen, it killed tons of life then caused snowball Earth they now believe where 95%+ of the Earth was under ice and wiped out 99% of life on Earth, mankind will never match that.
