DNA has an extraterrestrial origin

extraterrestrial alien dnaIf terms such as adenine and guanine bring you memories of the school course of biology, here you will see a reason to give to these words a second meaning. A group of scientists discovered that these two, as well as the other building blocks of DNA, can form in space and could have been brought to the surface of Earth by meteorites.

Meteorites found in Antarctica and Australia make scientists believe that the building blocks of DNA exist in space. In order to reach this amazing conclusion the researchers analyzed a series of 12 meteorites collected in Antarctica and Australia.

Inside, the scientists found a ‘treasure’ of molecules that may play an important role in the formation of early life forms. The adenine, which helps build the ‘stairs’ of the DNA helix, was present in eleven meteorites. The guanine, another key component of DNA, was present in eight ones.

Two of the 12 meteorites contain exotic particles that are very rare on Earth, thus demonstrating that the building blocks of DNA must have been formed in space. The discovery confirms the theory that a set of prefabricated sections on a meteorite or a comet could have given rise to life on Earth.

    the earth was formed in space from space particles,
    those particles now comprise part of the earth,
    and a subset of space/earth particles comprise DNA.
    What is the big surprise?

    Genesis 1:7
    So God made the vault and separated the water under the vault from the water above it. And it was so.
    Isaiah 40:22
    He sits enthroned above the circle of the earth, and its people are like grasshoppers. He stretches out the heavens like a canopy, and spreads them out like a tent to live in.
    2 Peter 3:5
    But they deliberately forget that long ago by God’s word the heavens came into being and the earth was formed out of water and by water.

    Not hydrogen, helium and lithium but hydrogen, oxygen and something in between. Not an explosion but being spread out. George LeMaitre’s Big Bang Theory is a poor copy for a Jesuit Priest who should have been reading his bible more vigilantly. Nevertheless created in space!

    Shallow, tabloid mag conclusion. There are billions of space bodies in the known universe – none harbor life: the unknown is more like the known than not so [math].
    Life is new on earth, probably a few million years, which is like .05 seconds of the earth’s age. For stray particles to form life, then billions of varieties, it would need a computerized brain or chip program that would exceed the universe’s capacity. We know that speech, unique to one life form, is less than 6,000 years – the oldest recorded name is Adam. Speech is the most powerful force in the universe. We are it – nothing out there detected for some 15 B years.

    This theory isn’t new, it’s called panspermia.
