this is what the world needs. thanks for sharing. we should endeavour to spread this light to all near and far. take care. all the best.

Why are human beings so fascinated by fireworks?

They're not fascinating, but they are bright, colorful and enjoyable. Think of them as the summer equivalent of Christmas lights. And no one wonders why we find Christmas lights so enjoyable. Or neon lights.

How long and how did the human eye develop?

Your view of eye development is wrong. Ancient humans were not blind. They had eyes already, inherited from the common primate ancestor we share with chimpanzees.

Eyes developed just like any other complex organ. Slowly, over many generations in incremental steps. Our eyes are not the only light sensing organ found among animals. By looking at other animals, we see many different types of eyes and we can put together a progression of more and more complex visual structures, each one built upon what evolved earlier. The link below has a nice video that explains it so I wont go into the details.

Instead, I want to point out some of the common but mistaken views of evolution by natural selection. Natural selection didn't make eyes because we needed them. Light sensing organs developed and were kept when they provided an advantage over their competition. The very first organisms that could detect light and respond to it would have an advantage over their competitors. For example, if photosynthetic bacterium could detect light and swim towards it, they would have an advantage over bacteria that swam randomly because they could not sense light.

A flat worm that could get some directional information would have an advantage over a competitor that had no directional imaging capability. Like the punchline to an old joke, if you're being chased by a lion, you don't have to out run the lion, you just have to be slightly faster than others to have an advantage over slower, more easily caught lion food.

And where did you get the idea that primates had echo location abilities? We have the ability to determine the rough direction of a sound source but nothing like sonar. Bats are mammals and they went down another path of variation where sensing sound gave an advantage in their situation. Eyes don't work so well in the dark. It doesn't have to be a perfect, working sonar right away, but an incremental difference (such as increased sensitivity or increased range of frequencies to hear insects better) provides a slight advantage over the competition.

Creationists are quick to jump to conclusions based on ignorance. Their entire argument is a celebration of ignorance. "It's too complex. I can't figure out how it happened so it must be magic." Of course we didn't go from nothing and jump directly to the eyes we have now. We did it in many tiny incremental stages. These intermediate stages are still around in different animal species.
