People with knowledge of evolutionary biology who observe the fossil record. I hate to state the obvious but the millions of species (many of them remarkably linearly similar ie. tree of life), did not spontaneously appear, and with the mechanisms of evolution, specism is inevitable. How else do you explain the snapshot of species we see today? How did they get there otherwise? This is when you seem awfully short of offering alternative theories after dismissing scientific consensus.
If you think the only evidence is that which a human being was standing there to see it, then you are dismissing probably most of science. And as usual you dismiss it without a snidge of personal research.
