These are at least five ways to construct and Aleph. One way is to construct it using a Vav a Bet and a Yud.
The Vav has a number value of 6 the Bet of 2 and the Yud of 10. Adding all of these up we get 18 the same number value as Chai- to live. 18 is also the number value of the molecular weight of water, essential for life.
