Explain the cosmological argument

Three forms of the cosmological argument: from motion; from causation; form contingency. First two respectively run as follows: (1) everything we observe in the world is moving/has a cause; (2) nothing can move by/is the cause of itself; (3) there cannot be an infinite regress of things moving/ of causes; (C1) there must be a Prime Mover/a first cause; (C2) this we call God. The argument from contingency runs as follows: (1) everything in the world is contingent and can therefore exist or not exist; (2) if things can not exist, there must be a time when they did not exist; (3) if everything can not exist, then there must be a time when nothing existed; (C1) things, however, exist now so there must be something on which all existence is dependent; (C2) this necessary being we call God.
