When one does historic analysis, and a group of cultures, who are related, all have a structurally similar rite, it is to be correctly assumed that that tradition are overlapping because the root culture (i.e. the culture the to be analysed culture group stems from) had this rite. For example, if we have Culture B and Culture C, who both stem from Culture A, and both are practicing structurally the same rite we can correctly assume that Culture A had this rite too.
Now let us look at the first homo sapiens sapiens in the fields and forests of Africa. Them being Hunter and Gatherers, they did not have the ability nor the wish to built permanent structures like houses. A great thing of importance for stone age and pre history human cultures is that the family was the center of everything, since you needed it for your own survival. A family would, when you will grow old one day, feed you and do things for you and it would preserve your species, which is a prime drive for any organism. With your family being important, ancestors would be held up high and their glorious actions would be reported of in the form of fairy tales to keep not just your tribe entertained but also your honor up. And due to honor and ancestors and nature being so important for these first humans, they erected things up for their glory, and to honor them post mortem.
They did not have anything permanent but things like cave paintings would be a permanent reminder of glory and honor, and they would be as permanent as nature and its spirits, which will become of importance later as the actions of ancestors become ever more extreme up to a point where they are held up as gods.
We can therefore argue that it is a ancient human rite to erect things to the honor of your ancestors, and with cultures and techniques for creating improving, more things could be built in honor of ones ancestor, and later their deities.
