The First Cause

There is a law of physics called "causation." It means, in a nutshell, that everything in the world must a cause. Even accidents have reasons why they ended up the way they did. If someone throws the dice and they land on 9, there were reasons why that happened. The force of the throw, the angle, etc. There is a reason for everything.

And there are reasons for the reasons, too. And reasons for those reasons. Nothing happens without a cause.

Now we have a question: If everything has a cause, and the causes also have a cause, and the causes of the cause also have a cause, etc – are the amount of causes in the chain of causes going all the way back infinite or finite?

Finite. Because it would be impossible that there were an infinite chain of causes without a beginning, for, as we learned, an infinite amount of things cannot happen - infinity is not the "biggest number"; rather, it is a number that can never be reached. Therefore, you can never have an infinite number of anything in this world.

And if so, if we cannot have a chain of causes without any beginning, there had to be a beginning - a First Cause, which itself had no cause at all.

This means, that this first cause has no reason or reasons for why it is; nothing created it, nothing makes it what it is. This First Cause is what we refer to as “Hashem”.
