Don't understand beginning of Prometheus?

In the opening sequence of the new Ridley Scott movie, Prometheus, a very white skinned alien standing by a waterfall drinks a fluid that kills him and then, once dead, his DNA appears to change in the water.

What is happening in this scene?

The Enginer drinks the fluid that breaks down his molecular structure, so he's basically commiting suicide. Except he falls into the waterfall, and the DNA recombines and accelerates evolution on this unknown planet. He's creating life.

I think it is mean to be the starting of the life on earth. That means life on earth started from the death of alien and his D.N.A has contributed in it. This is just my take.

His D.N.A is "seeding" the beginning of life on Earth
