Ven and good Buddha-Parisata,
In the case on whould say that the "Maha-Brahma Buddha" did not create existances and worlds, one would speak wrongly about the Tathagata.
This was said by the Blessed One, said by the Arahant, so I have heard: "I am a brahman, responsive to requests, open-handed, bearing my last body, an unsurpassed doctor & surgeon. You are my children, my sons, born from my mouth, born of the Dhamma, created by the Dhamma, heirs to the Dhamma, not heirs in material things... iti 100
He of course did not address those not related to him, outsiders, being still children, relatives of Mara.
And in this way he is also regarded by those in relation to the Tripple Gems. Without relation to him and his heritage, the Dhamma carried by the Sangha, one can never be helped by the Tripple Gems, having the Buddha as it's origin.
Other then ideas of people thinking they can just use what comes along, people of ingratitude, of no integrity, unrelated, the Buddha taught depended origin and right view, never denying duties in relations, parents, Brahmas, giver, goodness ...
He has right view and is not warped in the way he sees things: 'There is what is given, what is offered, what is sacrificed. There are fruits & results of good & bad actions. There is this world & the next world. There is mother & father. There are spontaneously reborn beings; there are brahmans & contemplatives who, faring rightly & practicing rightly, proclaim this world & the next after having directly known & realized it for themselves.' This is how one is made pure in three ways by mental action." ...(AN 10.176)
It is in dependence on me (the Buddha) as an admirable friend that beings subject to birth have gained release from birth, that beings subject to aging have gained release from aging, that beings subject to death have gained release from death, that beings subject to sorrow, lamentation, pain, distress, & despair have gained release from sorrow, lamentation, pain, distress, & despair. (Upaddha Sutta)
Feel given to ask for further explainings if still doubt and wishing to erase it.
