Struggling with variation with perlin noise and seeds

i have a 2d noise generator that generates 2d roblox terrain, the 3rd argument for math.noise is the seed but the issue with that is that it just acts like a z axis and makes any seed close to another generate very similar worlds

the seed is chosen through a random value that’s 1 through 100000000 and i’ve came across a few identical worlds every so often when play testing

i also noticed when changing the seed value manually that at a high enough number it’ll just be identical to any number that’s higher so i can’t just multiply the seed’s value to make them more different from each other

can you show your code? we cant really help you if we dont know you are doing things
