You can't honestly claim to have a linear idea or how a species evolved over time with a 99.9% incomplete fossil record. .1% of species that have existed have ever been fossilized. This fact alone shows the theory of evolution is baseless presumptuous garbage. "How else do you explain it?" is not an argument. There are countless plausible explanations. Believing the first plausible idea you hear or the only one you can think of to automatically be true is extremely hubris and midwit-tier reasoning.
