I like the idea of seeing life as deterministic or not. It's definitely a matter of "belief" when you put it that way. Although my scientific mind tells me nothing would exist if true random didn't exist. Thus the universe is not deterministic. But that's a question we'll never be able to answer anyway.

This is why I downvoted the parents by the way. I feel like there is no safe discussion when it starts with strong opinions ("which is completely untrue"). There is no right or wrong here so better be open minded.
