FWIW I don't see anything special in humans on the third rock orbiting our sun that would put us above or below any other being that knows and create from another planet (if they do exist). I would expect us to be very similar as there are natural requirements which exist within the laws of nature for intelligence to exist.
Yea but one scientist pointed out that they wouldn’t be human because they didn’t grow up here with our atmosphere or moon so while they may be made of the same stuff they evolved on a different planet that probably isn’t like it is here.
He said we assume they would have eyes because we do but maybe not. Things like that.
You have to go down the list of attributes required for intelligence to be able to emerge. For instance... #1 life must emerge from the sea. The physics of underwater living precludes intelligence from emerging. You will never see anything in the sea developing a technological society.
The next requirement (besides the sensory) is locomotion. Nature has selected quadrapeds because that is the most effective means of locomotion. I wouldn't expect that to be different. So they would have four limbs like us.
The next requirement would be a large central nervous system. Nature has selected warm blooded creatures for that. I wouldn't expect that to be different. So they would be warm blooded like us.
The next requirement and the most important requirement for intelligence to emerge is opposable thumbs. You can't have intelligence without it. They allow us to grasp objects and see them from different angles and perspectives. It is this that leads to our spacial awareness and intelligence. That's when all the magic begins. The nervous system of every single mammal has gotten larger as it evolved, but it was when the opposable thumb was introduced that our central nervous system took off. Everything about evolution points to the emergence of intelligence.
As for our senses, sight, smell, hearing, touch and taste, nature employs a back up system for each except taste. We have two eyes, two ears, two hands and two nostrils although the two sides of the sinuses are really about backing up the breathing capability. So I would expect that in these regards they would be similar to us as well.
Of course this all goes without saying that they would be carbon based like us as nature has determined that intelligence requires carbon based life forms.
