Place human the species in the order in which they appeared on Earth?
Humans, or Homo sapiens, belong to the genus Homo and have been present on Earth for around 300,000 years. They are believed to have evolved from earlier species of hominids, such as Homo erectus and Homo habilis. The exact order of appearance of different Homo species is still a subject of research and debate among scientists.
Who long has man been on earth?
Homo erectus came about 2 million years ago and they were the first generation of upright human beings in evolution.
Who was the first person or people on earth?
In the broadest sense, there was no "first person", even if we only ask who was the first person who was a modern human, a member of Homo sapiens. This is because we could not say definitively that this person was finally a Homo sapiens,but that his or her parents were still Homo erectus. Evolution is simply too gradual for such simple answers. What we do know is that the first Homo sapiens evolved over two hundred thousand years ago.We could regard our Homo erectus ancestors as people, although not yet modern humans, or even their Homo habilisancestors as people. Many scientists regard their more ancient predecessors as too primitive and too different to really be people in the sense that we usually use the word. So there would be a broad consensus that Homo habilis were the first people on earth.

What year was sulfur found in?
Sulfur was first identified as a distinct element (not as a compound of other elements) in about 1777, by Antoine Lavoisier.However, sulfur (which is the 10th-most common element in the universe) is naturally occurring, both in pure and compounded forms. Humans have used sulfur in its various forms for all of recorded human history, and well back into pre-history (it has demonstrated use back through our cave-man times). Thus, humanity first discovered sulfur at least 40,000 years ago, and likely it was used by some of Homo Sapiens' ancestor species before then (meaning, possibly back a million years or more).
