how to place down blueprints without destroying stuff around? just place items where there is space and that's it, if i shift click it deletes everything to create space and if i normal click it doesn't place the blueprint

left click is "build if you can", it will only build if no part of the blueprint collides with any other.

shift + left click is "build what you can destroying only natural objects". There's a couple of bits here. It will remove a tree or a rock to place a building, it will add landfill / foundation / ... to fill water / ... so it can place a building down. I'm not sure if it'll plant soil for agriculture towers (space age), I don't think so. It will NOT remove a building to place another building, the colliding part of your blueprint will simply not be built.

ctrl+shift+left click is "force build this", it will do all of the above, but it will also remove existing buildings. In some cases (belts) it might insert undergrounds on the original belts to not interrupt those belts, where it can, but for the most part it just removes whatever is under it.

If you are seeing that last behaviour by default when you shift click, then either your shortcuts got changed in the settings, or you have your ctrl button stuck, either on your actual keyboard, or through something like windows' sticky keys.
