First problem: ruby is case sensitive, so it wont work with Age instead age, If instead if etc.
Second problem: user input is a string, which cant be compared to a number. Lets say you enter "foo" how would you compare that to a number? you cant say that "foo" is greater or smaller than 18. If you enter a number, it is still interpreted as a string, e.g. if I enter "21" its still a string, not a number, and therefore cant be compared to a number. you have to turn it into a number using the to_i method. example:
x = "42"
y = x.to_i
puts x * 2 # puts 4242
puts y * 2 # puts 84
Refer to @MrCoder to see the correct code.

Your whole code should be:
age = gets.chomp.to_i
if age >= 18
puts "Welcome"
else
puts "Too young"
end

I am NOT a ruby learner,But I think this would solve the problem:-
1. age =gets.chomp
small a of age
2. convert age to integer, its in String
