Consider (1/x)^(1/x) = 1/(x^(1/x))
Since Limit(1/x=1..infinity) = 0, we have 0^0 = 1/(x^(1/x))
Then
Limit(x^(1/x),x=1..infinity) = 1
So 1/1 = 0^0 = 1

Empirically,
let x = 1000^y.  y=0..infinity
Then
The first 20 expansions of  (1/x)^(1/x) for y=0 are
1.000000000000000000000000000000000000000000000000000000000000000000000

Probabilistically, This evidence is so overwhelming that we can conclude 0^0 
= 1  in the same way
we conclude primality with the  ispseudoprime test. Or can we? Is the string 
of 9's 0.99999999999999999..9999.. = 1? Perhaps, if we argue that 1 is a 
better approximation than
any other number. In computer lingo it is 1.

Another point is to define  0 = 1/V. Where V is a Very large number so that 
resistence to  0^0 =
1  would be futile.

Could  0^0 be the creation = Big Bang = nothing to the nothing power?

Have fun,
