Well, so you made a mistake! And I still do not know why anybody realy
want to import data to Excel, if the data is already in R.
For me, the results are identical (and there is no reason why not).

See below.

You are right in the point what the code I sent does:
erg <- replicate(1000, {
x<-rgamma(10, 2.5, scale = 10)
y<-rgamma(10, 2.5, scale = 10)
wilcox.test(x, y, var.equal = FALSE)$p.value
})
sum(erg < 0.05) # 45
and it works for me. It results in a random number close to 50, hopefully.
Since both points above seem to be very strange on your machine: Which
version of R are you using? We assume the most recent one which is R-2.1.1.
