We're not alone obvi a giant ass universe, there's no way we're the only planet with people. yes it's a giant ass universe. so large that there can be billions of civilizations that are too far away to meet. Sucks that we don't have the tech to meet them! Do you think people know of our existence because they are technologically superior? I'm just a pessimistic layman. but here's the thing. the nearest star is 24 trillion miles away. I don't think we have visitors or will ever become visitors because of this Fusion Rockets can go to Alpha Centauri in 36 years. A laser sail with a sail that is 320 km (200 miles) in diameter would need just over 12 years. Meanwhile, a sail measuring about 965 km (600 miles) in diameter would arrive in just under 9 years. An antimatter engine would need 8 years. The Alcubierre Warp Bubble can do it in less than 4 years. If an advanced civilization could go to another star in just a couple of years, why wouldnt they? But there is a limit of how fast you can and the unrealistic needs of energy to get something like warp to be done in practice. If their planet is even just a 10000 LY away, it is really almost impossible to travel effectively unless they have something like generation ship or suspended animation. Maybe the live much, much longer than us.
