Odds don't come into it.  we've only been creating radio signals for just over 100 years, so anyone further away than 100 light years, even if they have the technology to hear us AND they're actively looking for aliens, wouldn't even know we're here.
Assuming someone on a planet 100 light years away hears us as you're reading this AND they decide to come visit us AND they have lightspeed technology (the fastest we believe it is possible to travel) then you're looking at a minimum of 2114 before they get here.
Even if they hear us and immediately send a radio message to say "Hi folks,  your BouyTax is overdue and we're coming to collect..."  We won't receive the message until at least 2114.

Geez, the last person I expected to come along and deflate perfectly good groundless speculation with logic is Cowbell Karyn. Everybody knows that aliens possess technology to bend the space-time continuum and appear instantly anywhere they like. Usually, over crop fields in England. Makes sense, given that all aliens speak fluent English. That's why they don't land in Scotland.

Hi,
 
Karyn ... time travel is not about clock time or light years, remember? ... well, in the stories, anyway!

As you've brought up time travel...  you can use it to prove that either the life span of our universe is finite, (it will end at some point)  or  time travel will never ever exist...
 
If the universe were infinite AND time travel is possible then at some point it will be created/invented and with an infinite future to come back from our current time should be totally over-run by time travellers,  which it isn't.
 
Therefore either, the universe is finite,  or time travel is impossible,  or both.
 

If you search sun and ufo or sun and ship and then sort through the riff raff, you will find that NASA has been observing odd happenings around the sun. This sounds totally crazy...I mean...the temperatures would do anything close by in you would think, but there seem to be pictures of structures that  seem to be using the sun......I'm not making this up.... or it could be a few kids who are good with photoshop...but NASA? Has me wondering a bit.

Traveling interstellar distances without messing with space/time is problematic for a number of reasons.
 
But if you can mess with space/time - and thus come whenever you want in time - why in the $%$%$@ would anyone want to visit us now?

Because if the universe were infinite there would be an infinite amount of time to %$&£ up and come here by accident, so we should be over-run by an infinite amount of time travellers complaining that they never intended to be here...
 
It does explain uBubba...  but where are all the rest?

The reason we can't get to other worlds is simple. It's by design you see. If we could reach our distant cousins amongst the stars the first thing we'd do is build a McDonald's there. After that, we'd likely try and figure out how to kill them - just in case. Eventually the politicians would find an excuse to try and kill them and steal their resources.
 
No, we're much better on our own. The aliens have already been here and said sod these fools, they have no moral compass, we're off.

backwoods100 million possible planets and somehow no one is advanced enough to be visiting us. What are the odds. Any scientists in here?

If you look into our past even further, you will see that aliens appear in our history, text and art and that they have been around for centuries, not just in the last 100 years.....
