Yes. It’s called nighttime.

Does this mean that we can see stars when the earth is blocking the sunlight?

When I was a kid I had a physics teacher who tried to get us excited with this theory. His argument was that the moon is
-
Perfectly spherical
-
Locked with one side that always faces Earth
-
Placed at such a distance that it appears exactly the same size as our sun in the sky.
I doubt that he truly believed it, I think he just wanted to make the subject more interesting for kids, but I've always been fascinated by astronomy, and the idea that things aren't what they seem is always cool.

I realise this now. I think it is now because the light from our sun washes out all other starlight.

Does this mean that at night, we would be able to see stars when the earth is blocking the sunlight from us?
Edit: reworded the question better.

I mean, James Webb and Hubble see a lot of stars from space

Light exposure. Big bright sun is much brighter so the dim stars disappear. Same reason you don't see stars during the day on Earth. Turn your phone brightness all the way down during the day putside and you will barely be able to see the screen if at all. Do it again at night in a dark room and that same setting is completely visible.

This doesn't make any sense for me. Light doesn't need something to see it. It's the other way around actually, the light bounces in the atmosphere and it's losing energy.

Thank you it does make sense that the sun washes out the light from other stars now.

Devils advocate... Huntsville has an overwhelming presence of exactly this type of work already in the full spectrum of industries relating to anything in space, from space, or about space.
Not only that, but the benefit of moving to where there already is a massive presence that will ultimately prove more efficient/useful is much more impactful than a building (or several) and 1500 people. Land is also extremely cheap, easy to develop, and generally unrestrictive.
The programs are what costs the real money, and being local to Research Park, Redstone Arsenal, UAH (albeit less important) is going to save plenty of money to make up for it. Several billion $ in programs going to significantly better use in a HUGELY more collaberative and resourceful area is much smarter than trying to save the paltry sum of what could even be a Space Taj Mahal made of marble.
Huntsville has been a massive hub for aerospace, medical, and defense tech for decades now. in 10-15 years it will be THE hub for virtually all things government contracting. A lot flies under the radar what Huntsville does, but taking a glance at how huge CRP is and how fast it is continually growing, and RA as well, will illustrate exactly why Huntsville is being considered.
Even manufacturing is seeing a boom. There are 20+ MM military/aerospace manufacturing start ups in the last 5 years in the region.
I think saying "renovate what you already have!" is incredibly short sighted. Take into account as well that just because they are basing out of somewhere else doesn't mean they have to completely evacuate their current home.
NASA has offices all across the southern US, including HSV, no reason they can't do the same. The delay in confirming the move to Huntsville is what's political. Everyone involved is inherently highly risk adverse and still its essentially a foregone conclusion.

How would anything happen if the moon gets holes drilled in it? It’s not losing any noticeable energy like the mass that gets sent back to earth so nothing would happen

A place to launch from does them no good if they don't have something to launch.

Pictures of other objects in space, say astronauts, are taken in the daylight so said foreground objects are lit. You don't see stars in the daylight on Earth (or large cities with lots of light pollution) either because they are to faint. Same thing applies to space.
The sky is black because the bright sun light is not scattered producing blue not because its dark.

Because most space pictures are taken during the day on their respective planet/moon. The sun washes everything else out, just like what happens during the day on Earth.

If you are in any kind of shadow, yes.
It's basically the limit set by the dynamic range of the optical instrument viewing. Given that sunlight is 60 million times brighter than starlight, it's no wonder that it washes out.
