This sounds like perfect XKCD "what if" material
Temperature is just atoms wiggling about. The more they wiggle, the hotter they are. By contrast, if they stop wiggling, have have reached the absolute zero point of 0 Kelvin. Things cannot get colder than that by definition.
This holds true both for the atoms in the air, and the atoms of your face. Atoms will bump into each other, and propagate heat to each other. The denser these atoms are placed, the more often they will bump into each other, and the better the material is for conveying heat. This is why metal can convey heat very well (and is super awesome to make a frying pan out of), while air is very bad at conveying heat.
When the sunlight hit your face, a lot of that heat will be absorbed as heat in your face.
When the sunlight hit the air, only a very little part of that will be absorbed as heat in the air.
Generally, the air will heat up very slowly, compared to a human out in the sun.
A fan by itself isn't changing any temperature. It is just moving air around. But by creating a wind, you are increasing the rate of which air collides with f.ex your face. When it does, heat will transfer from the air to your face - or vice versa, depending on which is hotter. Generally, that means a fan allows you to remove heat from your face, into the air itself.
If everything on earth had a constant level of heat, that fan isn't gonna do anything for your temperature. But luckily for your example, that isn't the case! Winds exist because of pressure. The sun shines on some part of the world, and not on others (due to clouds, night). In the areas where the sun shines, the air heats up, and gets molecules that get more .. speedy. They bump into each other more. And like a boiling water kettle, that hot air ends up spreading. Into areas where the air isn't as hot. This is what winds are.
Can you make your own hurricane? Certainly; a fan can do just that. But a normal fan isn't gonna cut it. Hurricanes are
stupidly powerful. Even a normal gust of wind can grant us enough power for humanity's current needs. Consider blowing up a nuclear bomb. That explosion will cause a monumental amount of heat, and a collosal wall of wind to match, able to knock over houses and whatnot. Yet a little over an hour later, the original wind is back to where it was.
To put some numbers on it, a cat4 hurricane is typically worth 1.5 * 10¹² joules worth of energy
per second. That's about 200x the amount of energy generated by the human civilization.
A nuclear bomb is worth 4.2 * 10¹⁵ joules of energy per
explosion. That's around 3750x as powerful as the hurricane - but a hurricane lasts for
days, far longer than that 3600 seconds = 1 hr. If you truly want to deter a large hurricane, expect to blow up a lot of nukes.
At least the following nuclear winter will solve the heat problem.

My question is:
Why is matter particles existing in space. Why can't it be that space is a field extending from matter?
