The Egyptians new because every year birds called the Ibises would fly by shortly before the nile was going to flood. Also Egyptian priests' would study the sky has part of their religion. They noticed that a star now called Sirius would show before the Nile would flood. Based on that they created one of the world's first calenders. It had 365 days just like ours.
Sirius
It is called Ursa Major.
It's not so much that the Egyptians thought their gods came from a star, as that the "underworld" which Ra crossed in a journey in darkness and day was seen as the night sky; hence the association with Osiris and Isis being with Sah and his consort, Sopdet; the Orion and Sirius stars.
Satet goddess of the the inundation of the Nile is depicted as a woman wearing a star on her head and carrying water jars.

Between the months of July and October, otherwise known as the Ankhet season.
Ancient Egypt needed to plan its events around the flooding of the Nile River. Its seeds had to be planted as soon as the flood waters receded. So they planned the calendar based on the annual flood. To make the date precise, they chose the date the star Sirius, or the Dog Star, rose at the same time as the sun. (Due to the wobble of the earth, called precession of the poles, it rose 3 months earlier 4,000 years ago than it does today. Like the Julian calendar, it would not be a good calendar to use today.)

The earliest Egyptian calendar was based on the moon's cycles, but the lunar calendar failed to predict a critical event in their lives: the annual flooding of the Nile river. The Egyptians soon noticed that the first day the "Dog Star," which we call Sirius, in Canis Major was visible right before sunrise was special. The Egyptians were probably the first to adopt a mainly solar calendar. This so-called 'heliacal rising' always preceded the flood by a few days. Based on this knowledge, they devised a 365-daycalendar that seems to have begun in 4236 B.C.E., the earliest recorded year in history.
That is the Greek name for that star. The Egyptians called it Sopdet.
