The idea of God always existing

[Mystic]

So how did the first point come into being?

It didn't come into being. It's the first point of existence, then time was brought forth. There was no before the first point by definition. The universe could said to have been the first point, but I don't see how time could've been brought into being by non-living entities. Surely matter doesn't have that ability.

And in what way this this first point shown to be worth praying to?

The first cause argument doesn't tell much of the First Cause other then it is uncaused and always existed and was timeless. Then other arguments tell you more like it has will since non-living entities can't just bring out existence from nothing or create time....

Does it prove he should be prayed to? No. Does it prove he is worthy of Worship? No.

There is other arguments for that, first cause argument proves a Personal Creator, it doesn't do much of telling us whether it's Perfect or Loving or anything like that.
