Are we alone in the universe? After NASA's discovery of new earth-like planet, Kepler-452b, Col. Chris Hadfield says "the odds are enormous" alien life exists somewhere.

there are like a septillion (1, 000, 000, 000, 000, 000, 000, 000, 000) solar systems in the universe (observable)... the odds are in favor for life

So many seem confident life exists elsewhere because other planets resemble ours. Now look up the probability of life. We shouldn’t exist. It’s next to impossible.

Yes! There is life out there. Now what happens to religion after they find life?

The observable universe is huge but the chance of abiogenesis to create a protein is so low. So far the chance of one celled life is low, the chance of intelligent life ( a mammal ) is much lower. If in the next few 1000 years we observe evidence of life, it will be almost impossible to travel to meet them or for them to meet us because light speed is simply too slow.

How often does abiogenesis happen though? Panspermia has spread life throughout the solar system. But has abiogenesis happened in other solar systems?
