How were we actually created in the world and who was the first person on earth?

It all began like 5 million years ago, from just one cell. This cell then merged with other communities to a multicellular being, and the same evolution continued till the formation of the apes. Then Natural selection (Adaption of an organism in his environment to survive) continued this evolution over million years, till the apparition of the Homo Sapiens, or as known today, the Humans.
Some Scientifics say that the first known human Ancestor is Lucy, is 3.2 million years old fossil found in Ethiopia in 1974.

Hope this Helps! :)

There are theories that say that as as humans were created from apes. That is what is commonly referred to as evolution or Darwinism. That is one of the most popular theories. According to the Bible, Adam was the first person on the earth. Adam was created by God (Jesus Christ) Cain was the first person BORN.
