but science still doesn't have the answer to life after death and why we exist here on this earth.
That is the "god of the gaps" fallacy. You think that because science doesn't have the answer to everything, it's acceptable to substitute mythology in the gaps. See, we used to do that with lightning, and disease, and how the sun worked, and science answered all of those in turn. If we don't know the answer, the appropriate stance is, "I don't know; let's keep looking," not just to make up an answer.
who are we? why are we here? what made us come here? what happens after we die here?
We are the species Homo sapiens sapiens, and we are here because hominids millions of years ego began to evolve increasingly high intelligence as a result of environmental pressures. In other words, the only reason we exist is because of the interactions of the physical laws. Do not pretend that we serve some greater purpose: if you see a rock on the side of the road, you would not assume it had a purpose. The human race, the Earth, and universe are just the same. And as for what happens after we die, since science has shown it to be pretty clear that consciousness is a function of the brain, and brain activity ceases upon death, it stands to reason death means the annihilation of the consciousness.
There is more to life then what are 5 scenes can hear smell touch taste and see. i think thats at least obvious because we are aware through science that there is many things we cant see like how small an atom is or little tiny waves or vibrations.
That's true, but the thing about science is that you still can't logically assert the existence of something without some demonstrable evidence. Take dark matter, for example. We can't detect it with any known means, yet we know it's there, because we've calculated that the outer-rim of the galaxy is spinning too fast for material gravity to account for.
