throughout human history, there has not been a single species that was observed "evolving" into something else. They have bred to be larger or smaller, or to have slightly different coloring, but the species never change. And never will. And never have.
But doesn't this "Evolution" thing make a nice theory? Except for where it doesn't.
That's not accurate. We have observed speciation.
Second, it's an absurd demand that we "see" lots of speciation in nature. That generally takes a lot of time. So, instead, we have fossils, showing what past species look like.
Wolves just appeared in the fossil record recently. Where did they come from?
The fossils showing species very similar to wolves, which also just appeared in the fossil record just before wolves, and then were gone before wolves...where did they go? And where did THEY come from?
Mammals were here before flowers. But leafy plants have been around longer than mammals. Where did the flowering plants come from?
