I do hope human differences are settled so the goal can be reached to travel in space and colonize other worlds, but my fear lies within not knowing if we indeed have the right "stuff" to do so. I hope we do. Can anyone shed some light on this for me?

The materials we do have. A propulsion system that can make a trip between star systems in a reasonable amount of time, we do not possess. Even if we do develop a means of propulsion that would work it would have to be operationally realistic eg a warp drive might work but would require the energy output of 100,000 sun-sized stars to operate, let's say. It's one of the reasons, it's hypothesized, that aliens never visited us.

OP we aren't limited by resources. We could build a solar sail / nuclear powered craft quite easily. The problem is that it would take hundreds or thousands of years to get to the nearest star.

what? at 10% c it doesn't take thousands of years... does anyone still read the thread?

forget the solar sail....

Project Orion.... BITCHES!

Of course it takes time to accelerate to 10% c. So it wouldn't be 10% all the way. But Orion accelerates quickly, so it should reach 10% within a year or two, depending on the size of the craft and the nukes used.

Also with relativistic time dilation, the journey would seem to take even less time.

E 2 = (mc 2)2 + (pc )2
614C → 714N + e + ̅νe
2 K(s) + 2 H2O(l) → 2 KOH(aq) + H2 (g) + 196 kJ/mol
It works, bitches.

There's no one on the Moon. Could it not be built and launched from a Moon base?

An elevator could filter supplies up to a storage and staging area in space, a shuttle could take crews and supplies to the Moon to build the ship and a massive platform from which to launch.

It might take a century to build and place that much crap but technology will have to advance parallel with such projects for many technological improvements to be made. Technology has the uncanny ability to make itself obsolete quite swiftly.

Even so, we still don't have a way to get anywhere in a lifetime. Which means that it's very unlikely that you'll see anyone opt to make the journey.

Alpha Centauri is possible within 40 years subjective.

Maybe. But a return trip still requires breeding of astronauts.
