Use the path exists builtin. Examples:

> "/home" | path exists
true

> "MRE" | path exists
false

> "./nu-0.71.0-x86_64-unknown-linux-gnu" | path exists
true

> [ '.', '/home', 'MRE'] | path exists
╭───┬───────╮
│ 0 │ true  │
│ 1 │ true  │
│ 2 │ false │
╰───┴───────╯
> [ '.', '/home', 'MRE'] | all {path exists}
false
> [ '.', '/home', 'MRE'] | any {path exists}
true

> if ([ '.', '/home', '/proc'] | all {path exists}) {
    "All directories exists"
} else {
    "One or more directories are missing"
}
All directories exists

(^Thanks to @Raze for the simplification using all.)

See help path exists for more details and help path for more path helper builtins.
