That is correct. Videos of apes acting intelligently does not prove that humans evolved from them. Luckily we have the fields of genetics, the fossil record, embryology, comparative anatomy, and others that provide adequate evidence to justify this idea.

Why is that luckily and why do you want to justify the idea? What's the point?

Thanks for asking, good question. The only point is to believe that which is true and not believe that which is false.

As long as you seek the truth, you should be fine. That's all that matters. That's what I believe
