Can you explain why there cannot theoretically be 2 gods who have equal power, are equally good, and so have no conflict or jealousy of each other?
Bismillah
Thank you dor your question. Such a conception of God is inconsistent with Him being Infinite, as to demark each god you would have to limit both of them to their own bounds so as to have two separate gods. This is why our ahadith explain that the Oneness of God is not numerical oneness, but rather the Attribute of Him being Infinite doesn't allow for there to be any god other than Him.
Philosophically speaking the hypothesis of two gods has no ontological justification and would need to be established as coherent and perhaps this is why no religious tradition i know of speaks of this hypothetical scenario as a reality.
May you always be successful
