Since 1992, scientific knowledge has been enough to determine the origin of life: ¡°life originated through RNA¡±. The truth is that current life world on Earth is just an RNA world, since the protein is created by RNA, then DNA as life¡¯s database is created by RNA along with reverse transcriptase (a protein of RNA making). The two life series on the planet originated through two RNA groups (named ¦²RNA ): I¦²RNA and II¦²RNA . I¦²RNA consists of the RNA members of the translational machinery (i.e., three kinds of rRNAs, 20 kinds of tRNAs, several ribozymes etc.) and the mRNA encoding an RNA replicase. I¦²RNA is able to produce the RNA replicase and then with this replicase I¦²RNA can also produce own template I¦²RNA. Thus its two tools (own template I¦²RNA and producing-force RNA replicase) arise. Two tools can in turn produce the template¡¯s prototype, namely I¦²RNA . So the prototype and its tools can produce each other, and the ¡°egg-chicken¡± replication loop is formed. From this time, the life arises. II¦²RNA consists of the RNA mem-bers of the translational machinery and mRNA encoding reverse transcriptase and transcriptase. This group is able to produce reverse transcriptase and transcriptase. Thus, two tools (template II¦²DNA and producing-force tran-scriptase) can also arise, which can reproduce II¦²RNA (the prototype of the template). Here, the prototype and its tools can also produce each other, and the ¡°egg-chicken¡± replication loop is similarly formed. Thus, life is also creat-ed. RNA viruses that do not involve DNA in their lifecycle belong to the I¦²RNA life series. All life on Earth, excluding the above viruses, belong to the life series that originated from II¦²RNA .
