I have an ancient laptop, need recommendations on which distro to install

I have a very, very old laptop with me. I don't know the exact specs, but it has a single core celeron processor and 4GB of RAM. It's an old little thing, maybe 15 years old.

I installed Debian on it with LXQT and it was chugging hard. I don't expect it will run modern browsers anyways, so give me your best distros that can run on a potato and have a GUI.
