"Religion" is the same as "form of worship." It is connected to the recognition of God, and formed by a set of intrinsic beliefs and practices.
From my point of view, religion existed since the creation of Adam, because he already had a direct relationship with his Creator, because he spoke with Him, and he had to obey his command as a son obeys his father.
When Jehovah called Abraham to make him the ancestor of a nation, He gave him orders such as leaving his homeland, wandering into foreign territory, circumcising all the males in his family, etc. Abraham offered animal sacrifices to Jehovah as part of his worship to Him. He taught his descendants about the true God, as Isaac his son and Jacob his grandson continued to worship and serve Jehovah following the tradition inherited from their ancestor.
As the people of Israel grew, they continued to worship Jehovah and offer animal sacrifices to him. They had different moral standards from the rest of the world and they took them seriously, as shown by the way Joseph acted when faced with the provocations of his Egyptian master's wife. After the Israelites left Egypt with Jehovah's help, their form of worship was formalized through a set of written laws.
So, no, religion is not an original human invention, but the form to relate of men with God, the true One, or otherwise, their other gods.
