Resetting Objects in a game

Using Wickeditor 1.19.3

Hello all,
I am teaching students in HS how to make video games using Wickeditor. My teaching example was created using the tutorial for ball dodge made by Jovanny. In my game to give it a complete feel I have added a play again button which I have send the game back to frame 1. However I’m unsure how to code the aliens to reset. Right now when the player dies and hits the play again button the game is reading the last known location of the alien and the ship which now causes an instant game over.

What have you tried so far?
I have looked at the code of several games and honestly I don’t quiet understand all the code in other games. This is my first experience with coding ever.

Thanks for help.
Mr.Dunn
