The Rule Explained
Lay is a transitive verb. That means it needs a direct object.
A direct object answers what? or whom?

Since the sentence has an object, lay is the correct verb family.
Lie is an intransitive verb. That means it does not take a direct object.
Example:
The dog lies by the door.
The dog is not placing anything. The dog is resting.
Here are the main forms:
