ANSWER: There is only One God (ALLAH), so men and women cannot become "Gods" and "Goddesses". However, according to the teaching of Shaykh Ahmad al-Ahsa'i, the "Faithful" (Mo'men) will inherit Paradise, and, in that realm (dimension) the mind controls and molds ethereal matter.
Whatsoever a Mo'men (faithful one) can imagine in his or her mind, that is created for them in Paradise. Thus, Paradise is like a very real and vivid dream-world which we can control with our own minds. For example, the "similitude" of a favorite pet can be re-created, or the "similitude" ofa lost love, or a child who died in infancy, or some particular life-story, etc. This is why this Realm is called Alam-i-Mithal (Arabic: "The World of Similitudes").
A Mo'men (Arabic: "faithful one") cannot create their own planets (as Mormons believe they will be able to do), but they can create their own "worlds" (surroundings) in the Realm of the Powers (Jaw-bawr-root); also known as "Paradise". This dimension exists in and surrounds our dimension (Nawsoot) in the Unseen World. While the teachings of Shaykh Ahmad al-Ahsa'i are not considered "infallible"; they were highly endorsed by Baha'u'llah, Who wrote:
"The followers of Shaykh-i-Ahsa'i have, by the aid of God, apprehended [understood] that which was veiled from the comprehension of others, and of which they remained deprived." (The Epistle to the Son of the Wolf, p.120)
