Why did the ancient egyptians use stone instead of wood?

the egyptians used stone instead of wood maybe because they had no wood supply in the middle of Egypt and stone was stronger and sturdier. if the egyptians were attacked or the tombs robbed the limestone would provide better protection. they used limestone because it kept cooler in the scorching heat and was easy to sculpt and break, however it was very heavy for the egyptian slaves to carry for miles and miles to the sites of the tombs.
