It's all about the mysterious ways of God. God has a plan and we are not to question it. It's a consolation to those who can't bear to live in a pointless universe ruled by nothing more than entropy.
Even people 300+ years ago were smarter than you.
Pascal's wager is an argument in philosophy presented by the seventeenth-century French
philosopher,
mathematician and
physicist,
Blaise Pascal (1623–1662).
[1] It posits that humans bet with their lives that God either
exists or does not.
Pascal argues that a rational person should live as though God exists and seek to believe in God. If God does not actually exist, such a person will have only a finite loss (some pleasures, luxury, etc.), whereas if God does exist, he stands to receive infinite gains (as represented by eternity in
Heaven) and avoid infinite losses (eternity in
Hell).

Pascal's Wager was based on the idea of the
Christian God, though similar arguments have occurred in other religious traditions. The original wager was set out in Pascal's posthumously published
Pensées ("Thoughts"), an assembly of previously unpublished notes.

Historically, Pascal's wager was groundbreaking because it charted new territory in
probability theory,
[4] marked the first formal use of
decision theory,
existentialism,
pragmatism and
voluntarism.
