Meteorites May Have Seeded Life On Earth

There is a distinction between Big Bang nucleosynthesis and stellar nucleosynthesis. The former produces hydrogen, helium, and small fractions of light elements such as lithium. The latter produces elements as heavy as iron during the 'regular' lifetime of an average star and elements even heavier during the late stages and during super novae.

Life forms must have come after at least the first generation of stars since they contain the heavier elements such as carbon and iron.

So, there is plenty of stellar 'garbage' contained within us lifeforms and perhaps some of the pristine lighter elements such as hydrogen from the Big Bang.

I don't think there is a way of being able to tell if the hydrogen within us is of the pristine type generated by the Big Bang and never incorporated into stars or if it is of the recycled variety that was incorporated into stars and later dispersed to become part of us lifeforms.

Agreed we should be more focused on the sun and the wind and hydro power= things that we dont have to disrupt so much of nature and earth to provide energy for us... you know that the human population is the biggest pollutant to the earth? And that the human population never crested 1 billion til we discovered fossil fuels... We used to live within our means instead of getting greedy and saying MORE POWER!

On the note of meteorites and life we owe it to meteorites for the formation of everything I mean go back to the Hadean and the evidence we have when earth was just a big ball of molten magma hotter than hell there was a collision and bacteria that adapted to survive these insane temperatures which created the beginnings of our crust... I mean really? Its rocket science but its not... We arent the only living things out there we are so self minded to think that we would be... and what about archaebacteria the extremists of the extremists the thrive on arsenic come on

 

one would have to be pretty narrow minded to think earth is the only place where life is the hevens are just to vast not to have life elsewhere and they allready know water is common in the universe.

 

This probably has more to do with the development of modern medicine that came along with the industrial revolution than just fossil fuels in themselves.

 

Just imagine....
what if another set of DNA was brought here by meteorite? Something that hasn't been introduced to Earth before....?
