Why does a cell tower need to be massive to transmit data to a smartphone but the phone’s extremely small antenna can transmit data back over the same distance?

Imagine you are communicating with people the size of ants. They have tiny ears and mouths, and you have huge, very good ears and mouth.
Since you are so loud, their tiny ears can hear you easily.
They are very quiet but you are above all of them and have very good ears, so you can hear them all regardless of their size. Your ears are specialized to the pitch of their voices so you can’t really hear anything else except their tiny voices and they are also pointed at a specific area on the ground, kind of like holding up a big cone to your ear.
