I'll try to explain it in few words. Seems like Otsutsuki clan from another world/dimension found the way to travel between them searching for something. A part of it came to the Earth and remained there, with princess Kaguya being their leader. Kaguya gained the power of Shinju via it's Chakra Fruit to spread her control upon the Earth. But outsode there were some other Otsutsuki descendants who were searching for the same source of chakra to gain the same power + get for themselves eternal youth and immortality and maintain them. We don't know for sure if these already were Momoshiki/Kinshiki or their ancestors (cause in the novel version of the movie Kinshiki mentions someone who eventually gave up his power to him the same way as Momoshiki was powered up via Kinshiki's sacrifice), but Kaguya knew they could come and take away the chakra from her, so she created the White Zetsu army from IT-affected people to battle them if nessessary. This never happened, yet when a millenium passed, Mo/Kin still arrived, although they seem to be surprised Kaguya is no longer there and the chakra was completely scattered among the mankind (which seem to be a problem for them, as they expected to extract it from a single entity - Shinju/Kaguya/whatever else), so they began to target these with relatively big amounts of chakra. (However, Mo commented it was still a small amount by their standarts.)
