How to perceive the fully cloaked master of the universe

[Purple Rabbit]

Some fellow human beings adhere to the stance that the alleged master of the universe has no attributes but existence, and even that according to them is just a matter of faith since existence cannot be perceived directly through the senses. Since ancient times there has been some development from the day to day god burning bushes in the backyard and giving clear however abhorrent and non-sensical messages and commands like slaughter your own son, to a much more cloaked version that leaves absolutely no CO2 footprint and somehow communicates silently in the heads of believers. I wonder, is cloaking a divine evolution thing?

Believing in such a fully cloaked god seems a real challenge to me. Since that god has no attributes but existence, how does it convey information, do miracles (that must leave a footprint), answer prayer and well, do what gods do?

(BTW: Why should his royal infiniteness limit himself to create just one universe when he can create many?)

And also why cloak what is important (or at least aspires to be)?

I hope someone here can shed light on the subject or we are all doomed.
