Everything is everything. The universe inside us is the same as the one outside us. A micro world within another world.
Imagine that right now as I write this there are millions of little creatures, microscopic in size who call our bodies home, but through creation and evolution have learned to work in harmony with us.
They probably have no understanding of us, just as how we still have so little understanding of our world and its connection to the universe.
Fractals are natures building blocks or blueprints that occur in progressively smaller scales. So imagine a square that becomes so small that the eye is no longer able to see it, but just because the eye is no longer able to see it doesn't mean that the square is no longer there or that it's a different square. It's the same square but is beyond the range of our visual comprehension.
Everything is everything. The universe inside us is the same as the one outside us. Maybe the earth is just another part of a living entity and we're just microscopic creatures living upon an earth that is an internal organ to the body of the universe...
