Can there be intelligent creatures beyond Earth??
why not ?
have we seen all of space ? ? ?
uhm no , we have only just begun
what i do find funny though , is they are only really looking for planets like are's for life (not to hot , not to cold and must have water)
but whats to say that they are based on the same things we are , there might be ones out there that live on a cold planet and breath nitrous
or are plant like and breath carbon dioxide , or be fur covered and eat cats (David), or live under a thick cover of ice and never come up out of the water
<shrug>
if we are the only ones out there , that is one big waist of space (forgot who coined that one)
