MY MINECRAFT MISTAKE

HELP! I'm stuck up here.  I forgot to build the ladders to down. And if I just there is a high chance I will die of fall damage.  Someone help meeeeeee!  I messaged my friend on social media to log on and help me. I was waiting for about five to ten minutes before he could log on. He wasn't the brightest of people. As he joined my world he flew over to my house and placed a 2x2 water source under my house thinking that I could jump into it. But because it was centered under my house I couldn't have made it if I tried. It was useless so I kicked him from my world and asked for help from my other friend. He logged on instantly and he joined my world. He played this game professionally and was really good. When his game loaded he flew over to me. he placed a sign to tell me to turn on my mic. I turned it on and he said " your in creative you noob XD." I laughed awkwardly and then flew down to the ground and built ladders up to my house and then logged off.
