Question

What was the probability that a planet like earth would be created after the Big Bang? What are the chances another planet like earth exists?

Answer 1

In both cases, it is a near certainty.

Explanation:

Consider that your average galaxy contains between 100 - 300 billion stars. Multiply that by the 50 billion (approximation) galaxies in the universe and simple statistics shows that other earths are extremely likely if not a sure thing.
