Who is Really Blind?

Introduction

For the believer, a scientific experiment can indeed prove the existence of God. For whatever you choose to test, and whatever the outcome may be, only the Most Capable has allowed it to happen- the fact that something happened is proof that Someone allowed it to happen. Everything in this universe obeys Allah, and the physical laws they follow are also their 'ibadah, are they not? Thus absolutely anything and everything that happens is a sign from Allah.
They may say that we humans and apes descended from a common ancestor, and that humans directly descended from other species close to us, despite the direct wording in the Quran that proves that Allah created Adam (a.s.) as the first human. I reject that notion as a believer, but I am still impressed by this fact that all species on earth can be grouped and those groups and even individual species' can be so linked to each other that we can prove that they're related or descended from one another. Is it not evidence for the One? For surely, if there were many gods as opposed to the One, you would've seen the world in chaos rather than such harmony, and if there were none, you wouldn't exist nor would the world.
They argue that billions of years ago, when the first life on earth was created, something happened that caused dead, inorganic materials to come together and become alive in the simplest form. Whatever the physical explanation may be, is it not evidence that Allah brings out the living from the dead?
But despite all the signs, most of them do not believe.
Thus, we will discuss whether Imaan is blind faith, or whether the people who turn away are the true blind ones.
We will first discuss about the concept of God in Islam, and Tawheed (the Oneness of God). Then we will discuss about the Messenger ﷺ, and then gradually about rest of the articles of faith in Shaa Allah.
