Funny question, since I often call God ''The Cosmic Shapeshifter''.
But, if I may...you are thinking in a limited 3rd Dimensional way;
thinking in terms of shape, size, color, up and down, there as opposed to here are all examples of limits.
I would say to you ...go within and in deep meditation ask God
to reveal Himself...He Who has no gender....but is Pure Spirit.
"Prepare yourself for the coming astral journey of death
by riding daily in a balloon of divine perception.
Through delusion you are perceiving yourself as a bundle of flesh and bones...
Meditate unceasingly, that you quickly behold yourself as the Infinite Essence"
~Lahiri Mahasaya, the Guru of Yogananda's Guru
I have no scientific evidence for anything I say.
