Using numbers proposed by scientists, (as referenced in the Wikipedia article on the Drake Equation), suggest that the Milky Way galaxy currently contains 15'600'000 currently active intelligent life forms capable of communicating to us.
Multiply that by the 200 trillion galaxies, and we reach a figure of 31'200'000'000'000'000'000 forms of intelligent life currently in existence.
I don't even know how to count that, lmao! Yet despite that staggering number there are still people that refuses to believe that we are not alone.
