Hi @irsyadul. You did a great job laying out three of the most mysterious events in the history of humanity. I would like to highlight two things though:

• It is crucial for any author of a STEM-related article, ideally any article on this platform to cite references.

• Make sure you abide by the law of using copyrighted material (in this case your image). Since you didn't cite your image's source, I would give you the benefit of the doubt that you're using the right kind of material for this article. Otherwise, if you couldn't tell, please refer to the post made by steemSTEM, by clicking the link below.

Please note that I'm not in any way, try to disapprove your work. You've done an excellent job here, but you can make it better. If you have any problem regarding STEM-related articles, you can join steemSTEM Discord Channel and we will glad to assist you.
