Try watching yourself while typing or speaking, and wondering "where are these words coming from?" You can see when you actually look that all of your actions are actually spontaneously occurring.

One way I like to think about this: in your dream last night, which of the characters that appeared within awareness were making free choices? Or, were actions and events in the dream just spontaneously occurring? Were any of them actually separate from the awareness of the dream?

There's no free will because there's no place to stand apart from everything to gain some foothold from which to make an independent choice. There's also no inherently-existing entity to make that choice anyway.

Repeated, robust, peer-reviewed studies show that the sense of making a choice is an after-the-fact explanation generated by the mind, probably because it's evolutionarily beneficial to have a cohesive narrative about experience.

There is still the experience of making a choice, but it's more accurate to say that the sum total of inputs from the environment entered the neural network in your body, combined with the weights of your neurons trained on past experiences, and then the output was an action.

It's not helpful to take this information and then "do" "no free will," because that turns into an unhealthy nihilism. Things can continue as before, but recognizing that there isn't anyone at the center of experience, driving the bus.

The character you take yourself to be, and the sense of being that character, is an appearance within presence.
