Can we ever understand the universe?
Darwin's theory of evolution explains very well the changes in species over generations and environment .
We now have DNA. Tools which Darwin did not have in his time. This puts us deeper into confusion.
We are now into the speculation hypothesis's:
How was the DNA. Written?
It was written by accident, lightening accidentally struck some inanimate object, water mixed with dirt brought fourth life.
This is quite similar to the biblical account of god said let there be light.
