The base of everything is answers everything about anything without science we would be like people who don't know any idea of anything and that is a problematic situation.

you could my suggestion somewhere near the beginning of the speech.
Science is indeed a key to all mysteries. Future is in hands of science. Yes, i knw science hav no hands. I meant that. Now a days science hav a lion share in contributing each and every sector in building a nation. Science often proves things that we claim impossible as possible. science makes wonders.
