So full disclosure I personally understand Bernoulli’s principle and understand how a wing works due to it.
Here’ is what I need. My 5 year old son loves planes, and loves watching birds fly. As such he is asking questions of how a bird’s wing works vs how an airplane’s wing works. I can’t seem to simplify down Bernoulli’s to the extent that he can understand how a wing works. So I’m coming to you all for advice.

Bernoulli’s principle for an airfoil shows that the airflow at the under section of the airfoil is slower and thus has higher pressure than the above section of the airfoil, so the air below the wing is essentially pushing up more than the air on top of the wing is pushing down.
For an actual 5 year old, I guess you could just describe it as some sort of tug of war between the air below the wing and the air above the wing? And the shape of the wing makes it so that one side is stronger than the other and pushes the plane upwards
