There are many experts (‘exoplanet’ hunters) who think that there must be forms of life somewhere other than earth and I’m happy to learn from their expertise. I don’t think it will look like us though – different niches need different lives. What do you think it would look like?
Although there may be other forms of life out there, I don’t think they would necessarily look like we do. Humans are the result of evolution on planet Earth, and therefore to look like us, aliens would have to be found on a planet with similar history to ours. Though this isn’t impossible, it’s more likely that they will have evolved their own special adaptations.
