Every serious examination I have seen on interstellar travel has revealed that it is not possible without great amounts of time involved. If we can't travel at speeds much faster than the speed of light then we aren't going anywhere which is pretty depressing to think about. Even getting humans to Mars and back is calculated to be impossible.
Mars isn't "impossible" it's entirely possible! Just really really expensive. It needs some things in place before it's remotely practical. Space elevator? Legrange spaceports? Moon bases for sure.
Meanwhile the time it takes to travel 1 light-year is critically important to whether aliens will visit us or not.
1 per hour? We'd be crawling with aliens long ago.
1 per day? They'd be here by the ton.
1 per week? Still tons of them.
1 per month? Getting serious. They for sure would be here already, just not a lot of them.
1 per year? Yeah, some would be here but not many. This could be our current situation. The few that arrive have spent a PILE of money & time on it. Whatever they're after must be really valuable to them.
Over 1 per 2 years means they would likely be few & far between.
👍🏼 Based on 30 to 60 light years distance.
Yeah, are sentient beings made of light? They're probably made of, you know, matter! And how long it takes a spaceship of any sort to travel 1 light-year is a critical element here.
Star Trek speeds? (I think they go like 8 light-years an hour?) We'd be crawling with aliens. 10 years to go 1 light year? Not so much.

Wut?
It takes light one year to travel one light-year, this is by definition what a light-year is.

The speed of light is the hard cap; we will never go faster.
All your estimates are way optimistic. It's more like 3-5 years for every lightyear, once everything is "perfected".
