Hi ron D and WELCOME to the forum.
Firstly, I have to agree with everything Titch said about the sewn in floor of your tent....IMO, it is a must have.
Secondly, I can't imagine you can buy a tent that does not have a permanently attached floor. If you can I would be interested in hearing more about it, what brand etc.
Thirdly, I deleted your other posting as I see it was repeated here which is a more appropriate place for it. You'll probably get more answers to your question here too.
