Seriously though, if you're lost in a cave you should probably stop walking any further. Just sit down and wait for rescue. And if you have any signal obviously call for help

EDIT

Here's what chat gpt says:

If you find yourself lost in a cave, here are some steps to follow:

1. Don't panic. Stay calm to think clearly¹.
2. Use any available light sources like a mobile phone or watch¹.
3. Protect your electronics by keeping them dry, such as in a ziplock bag¹.
4. Follow the airflow. Airflow can indicate an exit¹.
5. Look for cave clues. Caves may offer signs that can guide you¹.
6. Stay warm. Wear layers and keep dry to avoid hypothermia¹.
7. Mark your path. Use rocks or other markers to indicate the direction you've come from¹.
8. Stay together if you're in a group. There's safety in numbers¹.
9. Avoid wandering randomly. Stick to known paths or follow the cave wall⁵.
10. Shout for help periodically if you think others might be nearby⁶.

Always let someone know your plans before exploring a cave and bring the proper equipment. If you're prepared and stay calm, your chances of finding your way out safely are much higher¹.
