Mars is a far far far greater distance away from the sun than earth, but sceintists can record tempuratures of up to 65 / 70F in the martian summer. Perfect for sustaining life. If Venus's atmoshpere wasnt SO thick it could let off some gas and then the surface temp wouldn't be 400+ =)
So alien life would most likely be possible in conditions that are harmful to us. Though, i voted no because i thought the topic was about UFO aliens. :wink:
