More comments.....

The argument that says a virus has complete homology (similarity) to a
portion of human DNA....Thus cellular DNA - my be the creator of the

Can I argue other way round, that this - what we see is a result 
of a virus infecting cells and make itself  a part of cellular genome?  
Not the cellular genome giving rise to a virus?

To be able to prove your professor's theory.  I guess we have to 
get a "virgin" cell that never see a virus (may be from the Almighty...) 
and explore its genome.  Then get the virgin virus (again...from the
that never see a cell and explore its genome, and compare the two.

Since virus and cell must co-exist and one has to infect another,
and this has happened for million of years.  It is then - very difficult
to prove who give rise to whom.  Kind of like what comes first..chicken
or eggs.

What do you think?

Just my two cents...
