Why do men always have such a big ego to think that a woman is automatically going to be interested in them?

I got so many messages since I joined from guys who without having talked to me pretended like I would immediately be interested in them.

Then they say " you're very pretty but I noticed you're <<insert negative feature>> and I'm very traditional ".
And then they turn you down in that same monologue, as if they were having a conversation with you while you were not there.
I have noticed this quite often.

"You're hot but you live too far" , for example.

That is so weird.

Like , I don't even know you , never saw you.
Why would you think I would be interested in you?
You messaged me and made the assumption that I was going to be interested.
For all I know I could be way out of your league.

Why are men always so self-confident that even very unattractive men are so self-confident that they have the guts to message women who may not even be interested in them and who may be way out of their league?

That is not meant in a mean way but I notice that even attractive women will always doubt ourselves and always feel like we're never enough , whereas men , even the ones who should lower their standards, are always so confident in themselves.

It's almost ironic.

Is this something in the male brain structure , that guys are self-confident enough to go for women who are looks-wise much higher on the ladder than them, while women will always feel self-conscious , even when she's very attractive?

Is it something evolutionary?

Really trying to understand this.
I honestly would read a Ph.D study about this :D

Would love some healthy debate :-)
Healthy but polite.
