How big our planet is compared to our planets, and even stars?
On a human scale, the Earth is a rather large object and it has been humanity’s home since the dawn of the species. But, how does the Earth stack up on a Celestial Scale?
Now consider that there are at least 10 trillion planetary systems in the known universe. Notice the “at least”. That is 10,000,000,000,000. Earth would be “1” of those. The idea that there is no life on any of those other 9,999,999,999,999 planets is absurd.
