#2.708 xx 10^(-58)%# of the Universe.

Explanation:

If we consider the estimated size of the observable universe, which is said to have a volume of about (according to Wikipedia)

#4 * 10^71 "km"^3" "# (cubic kilometers)

and the fact that the Earth has a volume of

#1.08321 * 10^12 "km"^3#

then the percentage by volume the Earth occupies of this is:

#(1.08321* 10^12)/(4 * 10^71) xx 100% =2.708 * 10^(-58)%#
