For example, Genesis 1 doesn't describe God specifically designing all the animals. It just says that the Earth and waters brought them forth.
Ps 33:9 For
He spoke, and it was done; He commanded, and it stood firm.
you assume that what God speaks he does not plan or design. Without evidence.
Genesis 1 says
24
Then God said, “Let the earth produce living creatures according to their kind: livestock and crawling things and animals of the earth according to their kind”; and it was so. 25
God made the animals of the earth according to their kind, and the livestock according to their kind, and everything that crawls on the ground according to its kind; and God saw that it was good.
26
Then God said, “Let Us make mankind in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the livestock and over all the earth, and over every crawling thing that crawls on the earth.” 27
So God created man in His own image, in the image of God He created him; male and female He created them. 28 God blessed them; and God said to them, “Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the sky and over every living thing that moves on the earth.” 29 Then God said, “Behold,
I have given you every plant yielding seed that is on the surface of all the earth, and every tree which has fruit yielding seed; it shall be food for you; 30 and to every animal of the earth and to every bird of the sky and to everything that moves on the earth which has life,
I have given every green plant for food”; and it was so. 31 And God saw all that He had made, and behold, it was very good. And there was
evening and there was morning, the sixth day.
All that in a single "evening-and-mornding"
Gen 2 "More Detail"
7 Then the Lord
God formed the man of dust from the ground, and breathed into his nostrils the breath of life; and the man became a living person.
19 And
out of the ground the Lord God formed every animal of the field and every bird of the sky,
There is forming each of them from dust to living being. All in one single evening-and-morning -- day 6.
