Science fiction
If the aliens still have social life, they should have emotions and feelings like us. Emotions and feelings are building components of our existence. Thinking, memory, feelings and emotions processes could be differently functioning at aliens, and they might not have a lot of different feelings and emotions like us.
As I wrote before , we have more than 3K different emotions and feelings. Having more than 10K different amotions and feelings, could make us more human? It is difficult to answer.
We could not expect to get along with aliens if they visit us with their flying saucers ( flying objects, UFO ). We might be too primitive or too different because of our limited senses ranges and capabilities, and also because of the high number of emotions and feelings. The difference between aliens and us might be more than the difference between frogs and us.
If they existed couple billions of years before us, of course the biological and technological differences would be very big.
