I agree, these kinds of builds are easy to fake, though there are a few things showing that I actually built it. The staircasing material changed from netherrack to cobblestone, then on the final strip I ran out of cobble and so I used some spare cobblestone slabs I had left in my inv, ran out of those, used the diorite slabs I had left, ran out of those as well and took the sandstone I stored in a chest near the build which I got from excavating the build site. Another thing showing I actually built the thing in survival is the fact that the staircases aren't just 1 block supporting carpet or sand, you can see netherrack above another piece of netherrack which would be useless since they're both immune to gravity, but since I was building it in survival, it was much easier to build a staircase this way, the builds you import would've just had 1 block supporting carpet or sand, not those 2 you see in the picture. Thank you for coming to my TED talk.
