Yes gods exist.
Are they ultimately real? No.
The One God is The Ultimate Reality.
The entirety of psalm 82 reads...
"God standeth in the congregation of the mighty; he judgeth among the gods.
How long will ye judge unjustly, and accept the persons of the wicked? Selah.
Defend the poor and fatherless: do justice to the afflicted and needy.
Deliver the poor and needy: rid them out of the hand of the wicked.
They know not, neither will they understand; they walk on in darkness: all the foundations of the earth are out of course.
I have said, Ye are gods; and all of you are children of the most High.
But ye shall die like men, and fall like one of the princes.
Arise, O God, judge the earth: for thou shalt inherit all nations."
These gods are created beings. They come into existence, they have a time that they live, and they die. They are mortal.
So these "gods" are not like God. There is a world of difference.
