How can the Sun’s supply of hydrogen last for billions of years ? Does the Sun produce hydrogen as well as convert it to helium?  ?

    No, the sun converts hydrogen into helium, and hen it runs out oh hydrogen it starts to burn helium.

    Well, lets considere mass and volume of the Sun.

    It is huge. Please see picture below.It is mass to lasts more some billions of years!

    Mass of the sun = 1,989 E+30 kg.

    My guess is, hydrogen is drawn to the sun from other parts of space

    The Sun 🌞 uses Nuclear Fusion to produce Helium .. H2 is the first element in the periodic table... and the first element in the Universe ✨

    Because in only a fraction of the total volume of the sun the actual nuclear fusion is taking place, which is in the core. Only there the temperatures and pressure are high enough to make the fusion possible. But the rest of the sun is just a complete reservoir of hydrogen, with some helium and other elements through it, waiting to be fused as well. But since nuclear fusion creates this huge outwards pressure not all hydrogen can be fused at once. Still on average the sun convert 650 tons of hydrogen per second into helium. Looks a lot but if you look at the size of the sun, then it's just a tiny amount. The Sun does not produce hydrogen because it's already made of hydrogen.

    Because it is LARGE.  Very Large.

    It has a lot of it. Just like if you stock up on beans for your survival shelter. If you have a lot of beans, they last a long time.

    The sun does not produce hydrogen.  It uses what it has at a very very slow rate. Your average backyard compost pile produces more heat per kilogram than the sun! But since the sun is so large, and is such a good insulator, the heat accumulates inside the core and makes it very hot.

    The heat has to travel through 560,000 kilometers of very dense gas; it takes about 100,000 years for the heat to reach the surface. That's how good an insulator it is.

    The sun does not create hydrogen.

    It is, however, so incredibly massive, that the hydrogen available will last for billions of years.

    no, it does not produce it. 

    How? because there is a huge quantity in the sun, and nuclear fusion reactions produce a huge amount of heat for a small amount of hydrogen. 

    And in billions of years, when the hydrogen is mostly used up, new reactions that fuse helium start up. 

    You can find the numbers on the internet if you want actual data.
