What's purpose of your website? To provide proper information about your business, services etc.?
Yes, but only partially.

Let me present you my vision of the website that fulfills its purpose.

It's known that the people are target of a bunch of (irrelevant) information nowadays. Considering that, how to spotlight some information?

People are visual beings. "A visual effect is worth a thousand words", I would say.

Even more, website visitors want to interact with your website.
It's not enough just serve an information.

We are lazy to read, but are not lazy to scroll. So, why to write novels if our point can be memorized with couple of visual effects?

Since you have scrolled to the end, I've achieved my goal. And it was to keep you on website and present information that has almost nothing to do with the theme and animations implemented.

Just imagine your presentation website with information and animations combined the way they make sense!
