Once upon a time, there was a very smart scientist named Professor Albert. He was very good at inventing things and loved to explore new ideas. One day, he had a brilliant idea to create a time machine. He worked very hard and finally, he was able to build it.

Professor Albert was very excited to try out his new invention. He got into the time machine and set the date to go back in time. As he traveled through time, he saw many amazing things. He saw dinosaurs, ancient civilizations, and even met some famous people from history.

But as he traveled further back in time, he started to notice something strange. Every time he changed something in the past, it had a big effect on the present and future. For example, when he stepped on a butterfly, it caused a huge storm in the present. Professor Albert realized that he had to be very careful with his actions in the past.

He decided to go back to the present and try to fix all the changes he had made. But no matter what he did, there were always more problems that arose. He was stuck in a never-ending cycle of trying to fix the past, but only making things worse in the present.

Professor Albert was very sad and frustrated. He didn't know what to do. He realized that his time machine was more of a curse than a blessing. He had to make a difficult decision - to destroy the time machine and never use it again.

And so, Professor Albert destroyed his time machine and promised to never mess with time again. He learned that sometimes, it's better to leave things as they are and not try to change the past. From that day on, he focused on inventing things that would make the present and future better, instead of trying to change the past. The end.
