Best Answer

If there should be no space between the top rule and the text body use headsep=0pt as option for geometry. But the result looks strange ...

\documentclass[a4paper,14pt]{extarticle}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{parskip}
\usepackage{graphicx}
\usepackage[left=0.70in, right=0.70in, top=0.70in, bottom=0.70in,
  headsep=0pt,% remove space between header and text body
  headheight=17pt% suggested by fancyhdr
  ]{geometry}
%page style
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}% remove the default header and footer entries
\fancyhead[L]{left header entry}
\fancyhead[R]{\thepage}
\fancyfoot[L]{left footer entry}
\fancyfoot[R]{right footer entry}
\renewcommand{\headrulewidth}{2pt}
\renewcommand{\footrulewidth}{2pt}
\begin{document}
Starting of the document
