Pommoron,
Did you get that Dr. Suess?
Yes, the olderst known fossils is of bacteria. Thus they are the oldest life we have direct evidence of.
See http://www.wmnh.com/wmel0000.htm
But they were not the earliest forms of life on this planet.
In the Q&A section in Scientific American, you can find the following:
"We are in a similar predicament with our understanding of the origin of life. Since we don't have detailed information on the exact steps we will have to be content with developing plausible scenarios based on information concerning conditions on the early earth around the time life originated nearly four billion years ago. One plausible scenario holds that the first life on earth was based on ribonucleic acids (RNA), a simpler chemical cousin of DNA. Many researchers have focused on RNA because it can store genetic information and it can catalyze reactions; these are essential processes in living systems. In this scenario, it is proposed that RNA, a polymer (long-chain molecule), arose from the gradual stringing together of repeating chemical units, known as monomers, that naturally arose on the primitive earth."
See http://www.sciam.com/askexpert_question.cfm?articleID=00040547-723C-1C72-9EB7809EC588F2D7&catID=3&topicID=3 for the rest.
Obviously, scientists agree that the earliest life was not bacteria. who are based on DNA. DNA is way too complex to originate spontanously, as anyone should understand.
Many abiogenesis scholars also have suggested that the earliest forms of life were crystaline, not organic, and that organic life (carbon based) evolved by the aid of these earliest forms.
I think this was a far more serious reply than you deserved.
