Why did the human beings evolve into standing in an upright position not in the horizontal way?

To need arms to function as efficiently as humans do. To evolve horizontally would require support from four (or maybe three) limbs, and evolving a third set of limbs to serve as arms in very unlikely in a mammal. I don't think a six-limbed mammal exists...

One prevailing theory is that walking upright allowed our early human ancestors to use their hands for carrying objects, tools, and food while moving efficiently over long distances. This freed up the hands, enabling the development of more sophisticated tools and aiding in tasks like food gathering and hunting. It also gave them an advantage in spotting predators or prey over tall grass and savannah terrain.

Why not do the missionary position? It's a position just like all the others. Human beings are the only land mammals to have sex in this position, which is one more thing that separates us from the rest of the animals. While in the missionary position, both partners are facing each other which facilitates kissing and breast stimulation and allows both people to see each others facial expressions. I think those are all pretty good reasons.
