reasons of CAs in private lan?

hi
i don't understand well :
why i need a to request to a CA for a certificate
if i just try to secure communications
in my private Lan ... between 2 servers
why i need to involve a third entinty ?
are not my servers CAs
for my Lan by themselves ?
thanks
i will appreciate
