Did Comets Bring Life to Earth?

Understanding how life began on Earth engages many fields of science. It’s a complex question involving related bits of physics, chemistry, astronomy, and biology. Things have come a long way since the fourth century B.C., when Aristotle taught that life arose on its own from inanimate objects.





Critical findings of the past five decades all point to a picture of how complex, self-replicating cells could have commenced in Earth’s early days. In the 1950s, chemists Harold Urey and Stanley Miller demonstrated that small, life-related molecules, such as amino acids, could have formed under conditions likely present on the young Earth.

Difficult to place in reality, no scientist had withnessed it, thats pretty sure, so its an educated guess at best, who knows Earth is the last resting place for mankind in reach within a lifetime.

I remember reading recently that scientists found the basic building blocks for life on some recovered comets, so everything evolved from there.
Make sense, can't imagine what force in the universe would deliberately send us a Zuma..
