The Paris Olympics 2024 will be declared open, with a one-of-a-kind opening ceremony through the Seine River in the French capital.

Over 10,000 athletes are going to be a part of the process and will be carried in 100 boats which promises to be a delightful sight for all the fans across the globe.
