Fermi Paradox. Are there aliens? Of course. Are they in our current time and local space? Probably not. It's it fun to think about? Yes, that's why science fiction exists.
More importantly, are they a lifeforms that we would even recognize as alive? The chances of an alien being humanoid are even slimmer. Then there's whether they develop intelligence, whether they care about space, and whether they survive long enough to get anywhere.
It's a fair point, but I guess we would recognise them, especially if carbon-based.
Think of another issue. We evolved in 6 million years. Assuming it takes 4 billion for the planet to form and organisms to form, that means there's 8 bln years where civ can start. What's the chance that they are at a similar tech level as us? Really small.

Do you stop to talk to an ant on a field trip?
