There are many different types of aliens.
The most common ones (according to claimed contactees and abductees) are the “small grays” and the “tall whites”. They also claim to have seen mantids and reptilian aliens.
I have not seen any myself so I am relying on their reports.
But in your post 116, you claim that ‘they do not look or act human.’
So you are obviously making statements based on the mere ‘claims’ of others.
