So there have to be aliens because there are infinite planets, which actually hasn't been proven but whatever we'll just assume. So for every planet there's a tony chance there are aliens, you sample enough you gotta find aliens. Doesn't even matter how small the chance is.

Thought experiment time.

1. Even though the already small chance of there being aliens on a given planet becomes much smaller still if you generalize it to any given point in the universe, it's still nonzero, right? I mean maybe they're flying by in a space ship or boring through a planet's mantle in a high-tech machine.

2. Even though the already extremely small chance of the above becomes even smaller if you generalize it to a 4-dimenstional point in spacetime, it's still non-zero, right?

3. There's no fundamental difference if these aliens are actually living things or any other thing you could come up with, right? Suppose a piece of gold. The more specific you get, the smaller the chance but still nonzero. You could even look for specific properties, like a piece of gold of a particular size. As long as it's physically possible.

4. One of those properties could be velocity, right?

5. Given #2, you could choose up to 3 dimensions to specify and find a point along the fourth that matches all the given criteria, right? So for example, you could look for a piece of gold 2 miles across at the point where the Earth's exact center is now, and at some point in the past or future you'll find one.

6. Therefore, at some point in the past, at some point in space, there must have been a piece of gold 2 miles across traveling with exactly the right velocity to impact the Earth exactly as you finish reading this sentence...

Right?
