Answer 1
Whales first evolved roughly 54 million years ago.Homo sapiens (modern humans) evolved roughly 4 million years ago.
Answer 2
Whales and humans share a common ancestry in the clade of Boreoeutheria, dating back some 65 million years. By my best estimate, that's when the lineages leading to modern humans and modern whales went their separate ways.
Modern whales, like the blue whale, form a diverse group of species, just like modern apes, like the humans, form a diverse group of species. On a geological timescale, there may not be much difference between the emergence of the modern species of whale from their basal clades and the emergence of modern species of ape from their basal clades.
Comparing the emergence of modern humans to the emergence of whales isn't really a useful comparison. It's like comparing the emergence of vehicles to the emergence of the Audi A3.

The human race had treated te killer whales very badly because humans killed more and more killer whales than killer whales that had killed humans before.
