Spot the mistake...translation into english - who can help?

This is the story with all the corrections made:

Two unborn twins are talking in the womb of their mother:

"Do you believe in life after birth?"

"Sure I do. I think we are growing and becoming stronger to be able to face the world after birth."

"I think that is nonsense. There can't be life after birth. How would that work?"

"I am not quite sure but I imagine it as very bright. Maybe we will be able to walk around and eat with our own mouths."

"I've never heard of such rubbish. Eating with your mouth! What do you think we have an umbilical cord for? Oh, and speaking of umbilical cords, you CAN'T just walk around with it. It is much too short!"

"I am sure it is possible. Everything will be a bit different, but we will handle it somehow and discover new opportunities we could never even think of now"

"You are crazy! Nobody ever comes back "after birth". That's because there is nothing. Life ends after birth. That's just the way it is!"

"You are right - nobody knows how life will be after birth but I KNOW that we will see our mum. And she will care for us."

"Our mum??? Do you believe in a mum too? This is even worse than I thought. Where on earth shall she be? Could you explain that to me?"

"Everywhere. Everywhere around us. We live in her and through her. We couldn't be without her."

"Nonsense! I've never recognized a mum. She doesn't exist!"

"I have. Sometimes - when we are really quiet you can hear her sing and you can feel how she looks after our world."

"You are crazy! Nobody ever came back "after birth". And that's because there is nothing. Life ends with the birth. That's how it is!"

"You are right - nobody knows how life will be after birth but I KNOW that we will see our mum. And she will care for us."

"Our mum??? Do you believe in a mum as well? That is even worse than I thought it was. Where on earth shall she be? Could you explain that to me?"

"Everywhere. Everywhere around us. We live in her and through her. We couldn't be without her."

"Nonsense" I've never ever recognized a mum. She doesn't exists!"

"I have. Sometimes - when we are really quiet you can hear her sing and you can feel how she fondles our world."
