Wikipedia says, (I'm keeping it short):
Third way: The Argument from Time and Contingency
Summary
In the world we see things that are possible to be and possible not to be. In other words, perishable things. But if everything were contingent and thus capable of going out of existence, then, nothing would exist now. But things clearly do exist now. Therefore, there must be something that is imperishable: a necessary being. This everyone understands to be God.
To me this argument does not hold water, because it depends on what WE see, which is always limited if not distorted. What the argument shows is:
Since WE see things that are possible to be and possible not to be, etc,
WE should believe that there must be....a necessary being.
—What WE see does not prove what is fact.
Ask AI if that assessment makes sense.
