Okey, I have found an answer myself..

If someone looks for issue like me, read:

You have to create front-page.php and code there anything you want to display on front page.
than,
You have to code your main loop on index.php or home.php.. Which will display your posts.
and,
Lastly You have to change in backend(admin-panel) settings>reading> and configure there which page will display Your websites Front Page and which one Posting page..

Thats all..
