That’s a yes from me. But I wanna hear what others think.

But the other planets are probably absurdly far away. The space happens to be expanding as well, so that distance is also growing rapidly. If FTL travel isn’t possible, nobody will ever visit those worlds, and they can’t visit us. Just travelling at 1c or even 1000c won’t be much help either. The distances sure truly vast.

    They don't have to visit us to exist!

    The likely hood of said aliens visiting us is also zero.

    Care to elaborate? Why is it zero?

    Distance.

    Space is incomprehensibly big.

    I would say it’s probably close to zero, depending on what physics actually allows. If FTL travel turns out to be completely impossible, then it’s exactly zero. If some sort of FTL travel is possible, it’s slightly above zero. If you can travel faster than 10^9 c, that’s when distances stop being a huge problem. Before that though, distance ruins my dreams.
