This is a very simple thing to understand even for you humans and we really don’t want you to feel insulted, but your mental abilities are equal to the amount of intelligence you consider a chimp to have. You would be bored to death if you had to interact with nothing but chimps all day. This is exactly what happens to us with you humans. This is not an attempt to insult you, but to clarify with a good comparison.
We do care for you and we have watched you evolve enough to believe that in a few thousand years you will be more interesting creatures, but the evolution has been slow and you are still very destructive and selfish creatures. Until then we will continue to tolerate your behavior and allow you to stumble your way through evolution and we believe there is hope for your species to evolve into something worth saving.
