There are three major Abrahamic religions. They are Christianity, Islam, and Judaism. You may be thinking, "How are these religions similar? They have different beliefs!"
That is not completely true. They have similar beliefs: they are monotheistic (believe in only one God), believe in prophets, and all have a prophet called Abraham.
Abraham is where the word "Abrahamic" comes from. This one prophet is what links three of the most taught religions in the world.
