The Buddha has directly seen the origins of Maha Brahma and understands what it requires to be reborn in his world.
In the Brahmajala Sutta (DN 1) the Buddha describes how a supposed Creator God came to believe himself omnipotent and how others came to rely on his sovereignty. His description was based, not on speculation or hearsay, but on his own direct knowledge. The Buddha explains that when our world system disintegrates, as it regularly does after extremely long periods of time, the lower sixteen planes are all destroyed. Beings disappear from all planes below the seventeenth, the plane of the Abhassara gods. Whatever beings cannot be born on the seventeenth or a higher brahma plane then must take birth on the lower planes in other remote world systems.
Eventually the world starts to re-form. Then a solitary being passes away from the Abhassara plane and takes rebirth on the plane of Maha Brahma. A palace created by his kamma awaits him there: "There he dwells, mind-made, feeding on rapture, self-luminous, moving through the air, abiding in glory. And he continues thus for a long, long time." After ages pass, he becomes lonely and longs for other beings to join him. It just so happens that shortly after the brahma starts craving for company, other beings from the Abhassara plane, who have exhausted their lifespans there, pass away and are reborn in the palace of Brahma, in companionship with him.
Because these beings seemed to arise in accordance with the first brahma's wish, he becomes convinced that he is the almighty God: "I am the Great Brahma, the Vanquisher... the Lord, the Maker and Creator, the Supreme Being." The other brahmas, seeing that he was already present when they took birth in his world, accept his claim and revere him as their creator.
Eventually this misconception of a Creator God spreads to the human plane. One of the other brahmas passes away and is reborn here. He develops concentration and learns to recollect his previous life with Maha Brahma, but none of his lives before that. Recollecting that existence he recalls that Maha Brahma was considered the "father of all that are and are to be... permanent, stable, eternal." As he is unable to remember further back, he believes this to be absolute truth and propounds a theistic doctrine of an omnipotent Creator God (Net 69-70, 155-66).
The Venerable Ledi Sayadaw, a highly renowned Myanmar scholar-monk of the first part of this century, gave a careful analysis of the powers of Maha Brahma in his Niyama Dipani (MB pp. 138-39). He states that although Maha Brahma can perform all sorts of transformations, he cannot actually create independent creatures, change the kammic law of cause and effect, or keep anyone from growing old or dying. Brahma can use his special powers to transport a man to the brahma plane for a short visit, but he cannot ensure that someone will be reborn there.
If the creator of the world entire
They call God, of every being be the Lord
Why does he order such misfortune
And not create concord? sace hi so issaro sabbaloke

If the creator of the world entire

If the creator of the world entire

Sorry... if anyone wants to argue about this, can create new topic

I am merely presenting the Buddhist views on theistic doctrines.
