Panspermia as it is known today, however, is not identical to this original theory. The name, as applied to this theory, was only first coined in 1908 by Svante Arrhenius , a Swedish scientist. [ 14 ] [ 19 ] Prior to this, since around the 1860s, many prominent scientists were becoming interested in the theory, for example Sir Fred Hoyle , and ...
Pseudo-panspermia (sometimes called soft panspermia, molecular panspermia or quasi-panspermia) is a well-supported hypothesis for a stage in the origin of life. The theory first asserts that many of the small organic molecules used for life originated in space (for example, being incorporated in the solar nebula , from which the planets condensed).
Directed panspermia is a type of panspermia that implies the deliberate transport of microorganisms into space to be used as introduced species on other astronomical objects. Historically, Shklovskii and Sagan (1966) and Crick and Orgel (1973) hypothesized that life on the Earth may have been seeded deliberately by other civilizations.
Antonie van Leeuwenhoek. Traditional religion attributed the origin of life to deities who created the natural world. Spontaneous generation, the first naturalistic theory of abiogenesis, goes back to Aristotle and ancient Greek philosophy, and continued to have support in Western scholarship until the 19th century.

Intersex people have many different gender identities, [2] and so there is no presumption that people on this list have any particular sex assigned at birth, nor any particular gender identity. This list consists of well-known intersex people. The individual listings note the subject's main occupation or source of notability.
Panspermia did not get much scientific support and deflects the need of an answer instead of explaining observable phenomena. Although interest in panspermia grew when traces of organic materials were found in meteorites, it is currently accepted that life started locally on Earth.
Zecharia Sitchin (July 11, 1920 – October 9, 2010) [1] was an author of a number of books proposing an explanation for human origins involving ancient astronauts.Sitchin attributed the creation of the ancient Sumerian culture to the Anunnaki, which he claimed was a race of extraterrestrials from a planet beyond Neptune called Nibiru.
