would it be an infinite plan ? If so, how would it have affected or history? imagine an infinity of regions, countries and places ! I guess we would have discovered a lot of it by now. Also, the world would be oriented, with the infinite above and the infinite beyond. EDIT : also, rainbows would actually land somewhere, and the sun would be a ball of fire rising somewhere and sinking somewhere else
I think it should be exactly how it would have been for explorers who believed the earth is flat. Just Spain and then when you get to where America would be, you fall off the Earth.
