This answer is different based on your scientific/religious beliefs. Here are the varying answers.
Biologically, individuals belong to different *species* if they are unable to produce children who themselves can have children. For instance, when horses and donkeys mate, they produce a baby that is a little like a horse and a little like a donkey. We call the baby a mule. Mules are sterile and so cannot breed further - with each other, or with a donkey or a horse. Thus donkeys and horses belong to different species.
Where do these differences come from and how do they arise? The short answer is that they represent differences in the DNA found in horses and donkeys. DNA is the genetic code which specifies all components needed to "make" an organism. Every cell in your body carries your DNA which acts as a blueprint of how to make "you."
Over time changes occur in the DNA. These changes are the result of mistakes made when the DNA is copied from cell to cell, or of more "genetically traumatic" events such as large duplications or deletions in the genetic code (kind of like adding or removing a chapter from one of your textbooks).
It's important to realize that these mutations happen randomly. You can't tell when or where a mutation will occur. The effect of these changes is tested against the environment. Beneficial mutations, ones that help the organism survive and have children, are more likely to be passed on to later generations.
It's also important to realize that significant amounts of change happen very, very slowly, so slowly that it's impossible to see any change over a person's lifetime. Scientists must look at fossils from millions of years ago to note and appreciate the scale of evolutionary change. Humans evolved from a common ancestor shared both by us and by the apes we see in the world today - gorillas, chimpanzees, and orangutans. This common ancestor is referred to as Kenyapithecus. Its fossils have been found in Africa, and are ~16 million years old, indicating it lived 16 million years ago! Over time (millions of years!), subgroups of Kenyapithecus became sufficiently different that they could no longer interbreed (different species). One of these subgroups led to the line Homo - our direct descendants.
Members of the Homo line include Homo habilis which lived ~2.5 million years ago, and Homo erectus which lived ~ 1.8 million years ago. The first humans ( Homo sapiens neanderthalis) are believed to have evolved from Homo erectus approximately 500,000 years ago. Thus, the first humans appeared nearly half a million years ago. Who they were and what they did represents a large field of study, pursued by Archaeologists, Anthropologists and Evolutionary Biologists.

He was Born On Earth ! ....
Cain son of Adam
The Baby. Evolution tells us that new species evolve - so the first distinctly "human" person was born as a baby to a not-quite-human primate.
Sputnik 1 was the first Earth-orbiting artificial satellite and launched by by the Soviet Union on 4 October 1957. It was the first in a series of satellites collectively known as the Sputnik program.
because humons need to look after the earth
The first human which was born on Earth.
The concept of the "first human being" is based on the theory of evolution, which posits that modern humans (Homo sapiens) evolved from earlier hominid species. The exact timing and location of the emergence of Homo sapiens are still debated among scientists, but evidence suggests it happened in Africa around 200,000 years ago.
As per the scriptures, Adam was the first man on the planet Earth and GOD created him.
when the earth is born.........understand........born world born human......
well i think that god wasnt born first god created people and the first human being that walked on earth was Adam
No one truly knows, scientifically. In many religions, Adam was the first human on Earth. But nothing has been proven.
Yuri Gagarin was the first human both sent to space and also to orbit the Earth.
Adam
Adam was the first human on this planet
ADAM
Adam
This question makes no sense.
