If you need proof of anything
Of the existence of alien life,
Of the existence of God,
Of anything we know,
“Unrevealed manifestations of God's loving kindness will serve as garments that the pious will wear in the future . . . The parts revealed to man thus far in this world are merely to serve as an introduction to additional dimentions reserved for being revealed . . .” (Kedushat Levi on Vayetze)
Remember how much we do not know.
What we know is small. Combine yin and yang and find the gold.
The both sides of the coin are still a coin.
There is more. New materials that have yet to be rumored. Contradictions and paradoxes, just let them all be true.
