Is there any historical evidence or sayings that Buddha went to America and Africa continent for some discourses or teachings? In their writings, local languages or any painting, drawing?
There are various kinds of assemblies, O Ananda; assemblies of nobles, of Brahmans, of householders, of bhikkhus and of other beings. When I used to enter an assembly, I always became, before I seated myself, in color like unto the color of my audience and in voice like unto their voice. I spoke unto them in their language and then with religious discourse, I instructed, quickened, and gladdened them. But when I spoke, they knew me not and would say, Who may this be who thus speaks, a man or a god? Then having instructed, quickened, and gladdened them with religious discourse, I would vanish away. But they knew me not, even when I vanished away
"Ananda had asked the Blessed One how far his voice would reach in the universe. The Lord had answered that the Enlightened Ones were immeasurable and could reach further than a thousandfold world system (with a thousand suns, a thousand heavens, and a thousand brahma worlds), even further than a three-thousandfold world system. They could penetrate all those worlds with their shining splendor and reach all beings living there with their voice.
Ananda was delighted with this description, so all-encompassing and transcending all horizons, and he exclaimed: "How fortunate I am, that I have such an almighty, powerful master!" (AN 3.8)
