The outside world exists inside your head, but your head exists in the outside world.

In biology, the unitary approach makes it explicit why no organism can be thought of without an environment. An organism as a skin bag is no functioning system; it may be such only together with the relevant environmental parts. The same applies to neurophysiology or “cognitive” brain research: without the rest of the world the nervous system is not a system at all; neither is the agent of the behavior a part of the body, such as the brain.
Therefore your mind isn’t in your head; your head is in your mind.
There is no difference between you and the universe. What is you? Inside your brain, where are you? If that’s where you are, then your body is your environment. And if that is so, then the whole universe is your environment because every bit of it is needed to make you be here. Or, we could say the whole universe is your body. Either way works, but what we cannot do is draw a distinction between the two and claim you are somehow distinct from the universe.
You are the whole universe and if that is so, then the whole thing is a living system.
Of course the universe is alive. Stars are born, they eat, they grow old and die. They have personalities, they travel and raise families of solar systems and when a black hole moves into the neighborhood, they know it.
Life evolves from one to another and stars eat the gas and make minerals. Planets eat the minerals and make dirt. Plants eat the dirt and make sugar using radiation. Animals eat plants for the sugar and release the stored starlight. The whole thing is alive and it’s all dancing and doing its thing.
