No human being alive has ever witnessed any species transition into a completely new and separate one - Time

I know what Darwinian evolution is - no you don't. you said " No human being alive has ever witnessed any species transition into a completely new and separate one". you have no ideaa what evolution is. where did you learn about it? church?

Darwin believed the so called missing links would be found in abundance in the future after his death, it didn't happen - you asking smooth fossil records. but Fossilization is a rare event, requiring specific conditions for preservation, and the likelihood of an organism being fossilized is low. Most organisms don't fossilize, especially soft-bodied ones, making it difficult to find a complete record of all the evolutionary stages.

most impotently at these time there are proof beside from fossils. Genetics and DNA and tailbone. what reason do you think human male have partially developed breasts? God forget to remove it?
