Is there any proof apart from the bible and creation that a week has seven days. Like is there proof from the planets. And if not why does the whole world even those who had never seen the bible count a week as being seven days.

Problem is, they didn't (my emphasis):
An eight-day week was used in Ancient Rome and possibly in the pre-Christian Celtic calendar. Traces of a nine-day week are found in Baltic languages and in Welsh. The ancient Chinese calendar had a ten-day week, as did the ancient Egyptian calendar (…)
A six-day week is found in the Akan Calendar. Several cultures used a five-day week, including the 10th century Icelandic calendar, the Javanese calendar, and the traditional cycle of market days in Korea. The Igbo have a "market week" of four days. Evidence of a "three-day week" has been derived from the names of the days of the week in Guipuscoan Basque.
The Aztecs and Mayas used (…) weeks of 13 days (known in Spanish as trecenas).
