If you want to have a bigger chance of executing the script in a
POSIX shell.
This is the only way the standard provides for executing scripts:
If the execve() function fails due to an error equivalent to the XSH
specification error [ENOEXEC], the shell will execute a command
equivalent to having a shell invoked with the command name as its first
operand, along with any remaining arguments passed along. If the
executable file is not a text file, the shell may bypass this command
execution, write an error message, and return an exit status of 126.
A file which starts with #!/path/to/interpreter, is technically an
implementation defined file.
