How safe are planes flying internationally from europe to the US?

Ok I know this is funny, and I know that they say that planes are safer than driving a car to work everyday! But just to verify how safe are planes? I am flying out tomorrow from europe to the USA with Delta, how safe are their planes?
Update: Thanks so much! I feel better LOL I am flying with a 3 yr old and a 9 month old so obviously I am a bit scared! But thank you to everyone and to everyone who will respond to my question!
