Scientist Milton Wainwright suggested that small metallic spheres from space may have been engineered to carry DNA material. Wainwright’s proposal is supported by Francis Crick. Crick knows a thing or two about DNA having won the Noble prize on the subject in 1962.
Steven Hawking, like Crick and other scientists, have suggested that much of the life in the universe may be seeded by meteorites, comets and possibly even intelligent design.
The theory of Panspermia (meaning “all from seed”) was first purposed as early as the 5th century by Greek philosopher Anaxagoras.
“All things have existed from the beginning. But originally they existed in infinitesimally small fragments of themselves, endless in number and inextricably combined. All things existed in this mass, but in a confused and indistinguishable form. There were the seeds or miniatures of wheat and flesh and gold.”
Whether the silicone encasements purported to contain genetic material were made naturally or by some advanced civilization remains to be seen.
Reluctantly Wainwright admits:
“Unless, of course, we can find details of the civilization that is supposed to have sent it in this respect, it is probably an unprovable theory.”
