Invited talk among big shots, Nobel Lauerates

Post-doc in a STEM field. My advisor (and another faculty member) arranged a symposium in a big conference and put me  to give an invited talk in the middle of Nobel Laureates and near-miss Nobel Laureates ..  ( I know, I have the best bosses)

The talk is months away, but I can't shake the awkwardness of being the underdog in such a reputable selection. 

I am supposed to write an abstract for my talk but whatever I put down seems to be trivial and comical when I think about what the gods of the field will say.

Feeling very insecure, any advice is appreciated.

Have you ever seen a talk by a Laureate? They are usually a combination of old glories and mostly middling stuff that they are doing right now. Just present something new and exciting and you will look good.
