Because the use of these is restricted. Gov can only be created by the government, and Edu can only be used by registered by accredited educational institutions. Com, Net, Us, Vc, Tk, and many others can be registered by any "Riffraff" that wants one (or two, or three, or....) so these you may not be able to trust as much. Many are quite trustworthy, though--you just can't be as sure from the web address alone.
commercial websites base their information around selling their product

The most reliable domains are typically .gov and .edu. The .gov domain is used by government entities, ensuring authoritative and official information, while .edu is reserved for accredited educational institutions, reflecting credible academic resources.

The three most reliable URL endings are typically ".gov," ".edu," and ".org." URLs ending in ".gov" are managed by government entities and provide official information. ".edu" is reserved for educational institutions, ensuring academic credibility. ".org" is generally used by non-profit organizations, often focused on advocacy or public interest, though it requires careful evaluation for reliability.
Try a government site. There are many on the web. As long as the site ends with .org, .gov, or .edu it can be trusted and is reliable. Asking your family doctor may also help.
To get a backlink from .edu and .gov domains is a difficult task, the easiest way i recommend that you can gain such backlinks is by taking part in projects run by such .edu domains. By projects i mean most .edu domains are owned by Universitys if you some how contribute to projects that they are undertaking you will be able to place a link to your website from your profile page.
An easy way is with its Address URL end (.com,.gov,.edu,etc.) .com = they are trying to sell you something and they can lye but it can still be reliable sometimes EX: wiki.answers.com (they have ads) .edu = they want to teach you something, it is usually a school website EX: fcps.edu .gov= ITS THE GOVERNMENT, HIDE! (jk) usually a state website EX: http://sunbiz.org/
