Faith is the practice of acceptance without proof, similarly belief.
In terms of truth, both are somewhat futile...Which isn't to say, that a guess could not prove to be accurate.
Though beardy men basing a creation and existence hypothesis on a beardy man, was a lacklustre guess...But inevitable I suppose.
Nonetheless, in terms of an Earth related hypothesis, a Universal Super-Seeder is a reasonable suggestion.
Though depending upon the Super-Seeder's evolutionary heritage, it may well not be humanesque or bearded.
Might be reptilian or plant like or bacterial or other.
Of course, one cannot ignore the base origins of a Super-Seeder.
And the beginning is where all rational thought breaks down, and some beardy men et al, will always faithfully resort to beardy man.
