I honestly think, given the dire consequences of choosing incorrectly, that God has a moral obligation to be absolutely clear about his existence and the requirements for salvation from this supposed spiritual mess we are in.

Yet there are thousands of different gods and religions, and even within the mainstream religions there is huge disagreement about the Truth.

There is just not enough reasonable, undeniable evidence to be found.  Just what you'd expect if the gods were made up.
