"2- Beginning of the Universe"

If something has always existed it doesn’t need a creator.  In the first part of the 20th century some physicists held the view that the universe had always existed.  If the universe had always existed it wouldn’t need a creator.

However, according to Cosmology the universe had a beginning some 14 billion years ago with a cosmic event commonly known as the ‘Big Bang’[2].

Imagine you heard a loud bang, and you asked ‘where did that sound come from?’ Would you be satisfied with the answer that it came from ‘nothing’ and it ‘just happened?’ Of course not!  You would say ‘what was the cause of that loud bang?’ In the same way, rationally the ‘Big Bang’ must also have a cause that bought it about.  Now we can ask since the ‘Big Bang’ has a cause, what was the cause of that cause? Then we can ask, what was the cause of that cause? And so on and so on.  But this can’t go on forever and must end with a first cause, because of the following example:

Imagine a sniper who has just found his target and calls back to base to get permission to shoot.  The person at the base tells the sniper to hold on while they seek permission from someone else higher up.  So the guy higher up seeks permission from the guy even higher up and so on and so on.  If this goes on forever, will the sniper ever get to shoot the target?

The obvious answer is that he wouldn’t be able to shoot.  The only way the sniper can shoot is if someone gives permission without asking for anyone else’s permission.  That person would be the first cause of the sniper shooting.  In the same way, the Big Bang must have a first cause.

We can conclude that this first cause must be powerful as it brought the whole universe into existence, and it must be intelligent as it caused the ‘laws of science’ which govern the universe.  Also, this first cause must be timeless, spaceless and immaterial, because time, space and matter began at the ‘Big Bang’.  Finally, since it is uncaused it must have always existed.

All of these attributes of the first cause make up the basic concept of God.  God is the uncreated first cause of the universe.
