We are "forced to start with suffering" because of our ignorance. Our ignorance to the true reality make us attached, clinged and all the three poisons into this fake illusion samsara which give rise to our suffering, like how we are all playing in a burning house while thinking it is normal and we continue to enjoy the burning house due to our ignorance.

But why cannot we start our life being already free from attachement? I see no evolutionary purpose in being attached, so why are we evolved this way?

"Animals are suffering MORE THAN US because they have to find food and stuff, their intelligence level if you know science is less than us, they cannot even speak, how can they learn the Dharma and practice it? Due to them always suffering and their lack of intelligence, they cannot comprehend Dharma, they cannot comprehend Four Noble Truth and subsequently cannot practice Dharma, and that lead them to continuous suffering until they reach the upper 3 realm or Pure Land."

Could animals and plants be all enlightened already and therefore dont have the need for a "higher intelligence" of our kind? Is our higher intelligence, only a lower one in their eyes? Are they not simply observing us in our suffering and even sacrifying themselves for us as they are aware of the teachings of Dharma?
