Here's the Doctrine on it. Enjoy! John DOCTRINE OF THE ORDER OF BEGINNINGS A. John 1:1. The Greek phrase, EN ARCHE, "In a beginning which was not a beginning..." refers to the pre-existence of God. God always was; there never was a time when He was not. From the standpoint of chronology, this is the oldest verse in the Bible. Trinity always existed in eternity past. B. Gen 1:1. The Hebrew phrase BE RESHITH describes the beginning of the universe. It refers to the creation of the universe at some point in eternity past, time unknown. C. Jn 8:44. The Greek word ARARCHES refers to the creation of angels. From a beginning which was not a beginning in eternity past, the angels were created, time unknown. D. Mt 19:4. From the Greek prepositional phrase APO + ARCHES, we learn that man was created "from a beginning which was not a beginning" i.e., in eternity past. ARCHE means eternity, which is going on while time is going on. EN ARCHE <------------------------> NO TIME INVOLVED. BE RESHITH --------->. _____________________> UNIVERSE BEGINS APO ARCHE ---------->._____________________> ANGELS APO ARCHE -----------------------------> . __________________> MAN CREATED Last on the chart, Man.

It could have originated on Earth and elsewhere. It could also not have originated on Earth, and be brought there according to the Paspermia hypothesis: "The first known mention of the idea was in the writings of the 5th century BC Greek philosopher Anaxagoras. The panspermia hypothesis was dormant until 1743 when it appeared posthumously in the writings of Benoît de Maillet, who suggested that germs from space had fallen into the oceans and grown into fish and later amphibians, reptiles and then mammals. In the nineteenth century it was again revived in modern form by several scientists, including Berzelius (1834), Kelvin (1871), Greenberg, Melosh, and Hermann von Helmholtz in 1879 and, somewhat later, by Svante Arrhenius in 1903. Panspermia can be said to be either interstellar (between star systems) or interplanetary (between planets in the same solar system). Mechanisms for panspermia include radiation pressure (Arrhenius), lithopanspermia (microorganisms in rocks) (Kelvin). Directed panspermia from space to seed Earth (Orgel and Crick, 1973) or sent from Earth to seed other solar systems (Mautner 1979, 1997) has also been proposed. There is as yet no compelling evidence to support or contradict it, although the majority view holds that panspermia — especially in its interstellar form — is unlikely given the challenges of survival and transport in space. Sir Fred Hoyle (1915–2001) and Chandra Wickramasinghe (born 1939) were important proponents of the hypothesis who further contended that lifeforms continue to enter the Earth's atmosphere, and may be responsible for epidemic outbreaks, new diseases, and the genetic novelty necessary for macroevolution. This extension has also been adopted by proponents of Cosmic ancestry. Panspermia per se does not remove the need for life to originate somewhere, but does extend the time frame and environments available. Similarly, it does not necessarily suggest that life originated only once and subsequently spread through the entire Universe, but instead that once started it may be able to spread to other environments suitable for replication. (In the strongest version of panspermia, life never originated, but always existed — this axiom would require amending the big bang theory.) The mechanisms proposed for interstellar panspermia are hypothetical and currently unproven. Interplanetary transfer of material is well documented, as evidenced by meteorites of Martian origin found on Earth. However, claims that these carry evidence of extraterrestrial lifeforms — let alone viable dormant lifeforms — have either been proven unfounded as a result of terrestrial contamination, misinterpretation, or hoaxing; or are currently hotly disputed. Interestingly, space probes may also be a viable transport mechanism for interplanetary cross-pollination in our solar system (or even beyond). However, NASA has implemented strict abiotic procedures to avoid planetary contamination. - Evidence Until a large portion of the galaxy is surveyed for signs of life or contact is made with other civilizations, the panspermia hypothesis in its fullest meaning will remain difficult to test. There is, however, circumstantial evidence for exogenesis."

We usually use some models to explain what we observe. In this case, Panspermia could facilitate the propagation of life.

I believe it originated on Earth.

No, I do not. I believe that all life originated with the Lord Jesus Christ(see John 1:1-3), the eternal God Who later came to the Earth He created in a body of flesh, bone, and blood like our own(except sinless and perfect), born of a virgin, to die for our sins. Thank you and may God bless you. :) -In Jesus' Name.

Firstly, I am a Christian. I believe that our creator manifests Himself in many ways and that LIFE is the greatest of these. I also believe that He is omnipresent and that LIFE is too. I don't believe that life started just in one place and spread. In a nutshell, "Where God is, there Life is too"
