*_ Fallout on Alien Life Fossils & Meteorites
I read the paper by Richard B. Hoover, Ph.D. NASA scientist (link below)
"Fossils of Cyanobacteria in CI1 Carbonaceous Meteorites:
Implications to Life on Comets, Europa, and Enceladus"
Wow- what a discovery! Alien life fossilized in meteorites are found. E.T. is here! :) But wait- where is the evidence? These are not normal meteorites made of metal and rock. They are soft coal clay with old bacteria fossils inside. Is it likely or even possible for local meteorite debris to contain alien life fossils from other planets? Where do most local asteroids come from? Pieces of asteroids and moons were broken off, spat out, or left over from early formation of planets in their orbits- such as Earth and Mars. The Asteroid Belt beyond Mars is a planetary orbit that never gathered enough mass to collect the accretion disc of rocky asteroids. The majority of asteroids near the Earth's orbit are from local Earth to Mars to Asteroid Belt space. The Earth sweeps up a few asteroids and comets that are ancient wayward travellers from outside the inner solar system. It is improbable that more than a few meteorites hitting Earth originated outside the near plane of our solar system. Meteorite samples must come from local planet and asteroid debris, not an alien planet of unknown origin.
We are Stardust.
Upon seeing an exploding supernova, am I witnessing the hand of God giving birth to ubiquitous elements- building blocks of our physical world and life on Earth? If so it follows that we are made of Stardust. Even in different environments on other planets, their chemistry is the same as ours. They are Stardust. From millions of supernovae stardust, organic life may exist across a vast universe of billions of planets. However numerous alien life may be, logically vast distances of space and time separate Earth from alien life on other planets. It is likely that any organic biomarkers or bacteria fossils found here are not alien. They originated on Earth itself and were ejected, or possibly formed on an earlier local planet preceeding the modern solar system. Any life we encounter in or near our solar system is probably our own ancient relatives coming back home. Another popular theory of finding bacteria on Europa or Mars is possible- not alien life but sharing a common local ancestry. Perhaps this is our destiny- to colonize nearby stars and split into new planet ecosystems. Later only to rediscover distant lost cousins and strange but related life.
Are alien fossils here?
Totally alien life arriving here on a rogue comet would have to be very old- older than the solar system itself travelling at speed to reach Earth across deep space. Though alien life might be in the millions it would be too far away to reach us easily. Given that vast distances separate us from most of the universe, it is extremely unlikely we would find alien fossils in local meteorites.
Nice clay-theory play. But no pay day.
Amazing how these carbonaceous meteors are identical in chemical and mineral makeup to coal and aqueous Earth clay containing perfect fossilized bacterial Earth life. Is it then similar but alien fossils? Where is the proof? There are no other places or planets in the solar system containing identical clay and coal material besides the Earth itself. These carbonaceous coal-clay meteor fragments with distinct Earth bacteria fossils could only have formed in Earth clay and Earth coal derived from Earth organisms.
This is obvious. It is astonishing to see a distinguished scientist ignoring what is right in front of his nose. The good scientist's claim to have discovered alien life is built on mere speculation and the absence of disproof. But it can be disproven once the fossils are matched to specific Earth organisms. Positive evidence is needed for the paper's main premise of extra-terrestrial origin of fossilized bacteria- but there is no such proof at all. For example, actual positive evidence of alien life might be found by taking direct samples of asteroids and comets in situ never touched by Earth contaminants or ejecta. As stated by the paper, the carbonaceous meteorites are unlike 99% of other asteroid parented meteorites- so must be something different. They turn out to be identical to Earth clay and coal, and amazingly contain fossils identical to Earth prokaryotes and organisms. The real significance is the carbonaceous meteorites are a valuable ancient fossil showing our long history and that fossils (in this case from Earth) may exist in meteors.
A claim is made that if a rock falls from the sky it must be from an alien planet. Eureka- a great modern scientific discovery- alien life fossils are found! But the obvious truth is that the meteorites are simply a rare chunk of Earth mud batted out of the ball-park that has returned to home plate.
The Rock Stops Here.
Therefore these fossil meteorites originated on a parent planet- as stated by the NASA scientist's paper. Not from another alien planet, but rather the fossil meteorites must be ejecta from planet Earth spat or smashed into local space and then swept back up by mother Earth. No aliens here, but maybe when we travel to other stars we will find the real thing.
Questions for further study _______
*_ How old are the carbonaceous meteorite fossils? Do they pre-date identical known fossils? The article says they align in time with similar bacteria but then suggests much older space rocks.
*_ When I see a falling star (a meteorite), am I witnessing the hand of God re-enacting the genesis of life on Earth?
*_ Were the seeds of life on Earth planted by life spores from other planets? Are meteors a mechanism of cross-transfer spreading organisms between other planets and the Earth?
*_ Go beyond dead fossils ejected from planets. Can living organisms survive inside comets travelling the stars and dust clouds? Like microorganisms suspended in a tiny drop of water on a leaf in the wind, could comets transport alien life across deep space?
