Does E.T. Exist?

During breaks while working on the construction of the first atomic bomb in 1943, Enrico Fermi and his colleagues talked of many things.  One of which was alien intelligence. 

The Milky Way galaxy that we live in is easily large enough to house millions of civilizations and is certainly old enough (about 13.5 billion years old) so that one of them should have colonized the galaxy by now, so Enrico asked, “Where are they?”  This questions is now known as the Fermi Paradox.

Let’s talk about the possibilities of collisions with the Earth.

Actually, our Earth is being hit all the time by cosmic dust and meteors. More often than not, these will fall into the atmosphere and burn up, producing a streak of light in the sky we call a “shooting star.”  But sometimes the chunks are big enough so that part of the original chunk gets through the atmosphere.  Anywhere between 5 – 300 metric tons of dust and meteors strike the Earth per day!
