I’d repeat what this wall decal says: what we have is from another planet. NASA can spend all the money in the world to get to Mars, but if they really want to see extraterrestrial life, they should come round to our place.
These wall decals are super easy to put up, and you can hang them inside or outside. The decals are washable and last a lifetime, and if you get bored of them (which is highly unlikely), you can take them down without leaving a trace.
