Reason?

So the question is, what is the reason for the ark gods to take an ark full of technology and genetic fragments, need to break through layers of barriers, enter the solar system, and even need to sacrifice the Pangu God; After the Ark entered the solar system, the incubator that provided the continuation of the race was completely destroyed, and since then, the race God has lost its reproduction function, and it has to spend huge resources to transform the environment of the Earth, creating single-celled life on the earth to fuse with the genes of the Ark, thus creating the genes of the race and the continuation of civilization.

If you think about it, there are only a few possibilities: first, colonization; second, flight. The former, as star pioneers, try to obtain more resources, is a basic requirement of colonization, but here is a case worth thinking about, that is, if it is colonization, why the ship has a large gene pool? The only explanation is that the species is going extinct, just as in the Bible, God wiped out humanity with a flood, except for Noah's family. The story of Noah's Ark is well known in the Bible. When God decides to unleash a flood to exterminate humanity because of its misdeeds, he chooses a man named Noah to build an ark so that his family and every animal can escape the disaster. In fact, the reason is the same, the species preserved in the Bible and the gene bank preserved in the ark are the same reason, in order to allow civilization to rise again. Therefore, the practical reason is that this civilization entering the solar system is a civilization that is about to be destroyed, and we humans are the continuation of this civilization.

The imprint of the destruction of civilization is deeply engraved in the minds of the great gods, and every race and civilization hopes to return to their own universe and home planet and create humanity for two purposes: first, to provide a possibility for the continuation of their own civilization. Second, the higher species created humans to manipulate weapons, to serve as cannon fodder as soldiers on the front lines. Either possibility is needed for the higher races.

In addition to the first case, let's focus on the way in which the front-line warrior, this warrior, participates in the confrontation of the higher races, or in what way does the higher races control the participation of mankind in this war?
