Hmmm, relative to heaven all incomers will be alien.
It's a tad arrogant to assume that Heaven is a human only resort....Just like it was a tad arrogant to assume that the creator thingy was a man, solely based upon the notion that there was a creator thingy in the first instance.
Same applies to avian existence...Though I'm guessing that it's still probably wise to not choose the same hotel as the Eagles...Find one with a pool, that caters for aquatic vegetarians...Though if you are an adventurous sort, you perhaps wouldn't mind mixing it with insectivorous songbirds...Better karaoke...But just stay of the mic... Quack quack quack, won't be appreciated.
